Teresa is a sneaky conniving person with how she always lie to everyone to get what she wants, but sometimes the things we need can be harder to get. As Teresa was getting herself ready for another, she saw breakfast was placed out for her and a message from her mother saying she wasn't going to be home tonight. A mother not being around so much can be hard to handle. Teresa might be an awful person, but it would seem she does have a heart as she didn't like that message. Once she got her breakfast, she was just on her way out and headed for school, but sulking about her mother.

"Teresa! Wait up!" Gray called as he spotted her and chased after her. "You doing okay."

"Oh, I'm doing just fine, Gray." Teresa said. "It's just that I've been having some trouble with in a couple of my classes, and I was thinking of asking Natsu to help me out. I heard that Natsu gets good grades." She lied again to hide what was really going on."

"Yeah, another requirement of his brother." Gray said. "He says that Natsu has to keep his grades up if he wants to stay in public school. I'm sure he would be willing to help you out."

"I do want to ask him, but I don't want him to think I'm one of those fan girls that just want something out of him." Teresa said.

"No problem. I can just talk to him for you." Gray said, not knowing he's just being a pawn in another one of Teresa's schemes.

...

The School

School was coming to an end for the day. That means that Teresa's plan to get closer to Natsu was about to happen.

"Hey, Teresa." Natsu said as he walked over to her. "Gray tells me that you might need my help with some tutoring." While the two were talking, Levy was on her way out. However, she spotted Lucy acting sneaky as she tried to get as close to them as she could without being spotted. Lucy snuck behind the back of the seats and tried to keep hidden.

"Are you actually spying on Teresa and Natsu?" Levy teased as she joined her.

"No... I just... I just..." Lucy said as she was trying to come up with a good excuse for this.

"You don't have to worry. I heard that Teresa has no interest in Natsu." Levy claimed.

"I know you think differently, but I don't really trust her." Lucy said as she knows what Teresa is like. She tried being quiet and stealthy, but Teresa was actually aware they were back there and she wasn't going to let Lucy get in her way.

"You know what, let's go to your place, Natsu." Teresa said as she grabbed Natsu by the arm and practically dragged him out of there, but Lucy wasn't going to let her escape that easily. Teresa and Natsu ran out to his car, but Jacob stopped them.

"What's going on here? You're suppose to be straight home, Natsu, and she's not coming." Jacob said.

"But we're going to do some studying. It would really help me and Natsu." Teresa said.

"Teresa, you might as well stop. Zeref isn't going to like you in our house without his permission." Natsu said.

"You just leave that to me, Natsu." Teresa said. "Listen, sir..." While she was talking, Lucy stopped just short of the school entrance and saw them.

"There's no way that Natsu's bodyguard is going to let her through." Lucy said. She was sure Teresa would be stopped there, but whatever she told Jacob worked. Teresa was able to get in the car with Natsu. Lucy couldn't believe it as she watched them drove away. "How does she do it?!" Lucy couldn't let this keep going and just kept trying to follow them.

"You should trust that Natsu should handle this, Lucy. He knows Teresa is a liar." Stella informed.

"I do trust Natsu, but I don't trust Teresa." Lucy said. "She'll stop at nothing to get her way." Knowing what that girl is like, and refusing to let Natsu get played, Lucy hurried as fast she could to Natsu's house.

...

Natsu's House

Jacob went on ahead with this and soon brought Teresa to Natsu's actual house.

"Teresa, this isn't a good idea. My brother isn't going go through with this." Natsu said as he just knows what is going to happen with his brother.

"But we're not doing anything wrong, Natsu. We're just going to do some studying." Teresa said. "Just let me do all the talking." Natsu wants to believe the good in Teresa, but he's getting a bad feeling about this. The three of them walked inside where Invel was waiting for Natsu.

"Welcome home, Natsu. Your brother is..." Invel was about to rundown the schedule, but he soon spotted Teresa. "What is this? Why is this girl?"

"Hello. My name is Teresa and Natsu invited me over."

"Young lady, Mr. Dragneel does not like having people in his house without his acknowledgement or his permission." Invel said.

"I understand, but I'm here to do some studying with Natsu." Teresa said.

"Even so, Natsu can handle his studying alone." Invel said.

"I see." Teresa said as she acting like she failed. "I'm sorry, Natsu. I know I said I help you get your grades up, but it looks like it won't be happening today."

"Help, Natsu?" Invel questioned. "Natsu, have your grades been suffering?"

"I'm afraid so." Teresa said before Natsu could say anything. "He's too ashamed to say anything to his brother, but I agreed to help Natsu. However, I don't want to impose on Mr. Dragneel. I'm sorry, Natsu, but it looks like I can't do anything about it today, and with your busy schedule, I'm not sure I'll be able to get another chance." It looked like Teresa was playing Invel and it worked. He actually considered sneaking Teresa in as he looked towards where Zeref was working, but knew they be in big trouble for this.

"Very well, but it will have to be for a half-hour." Invel said.

"Thank you!" Teresa said as she pretend to be happy while really being smug.

"What was that?" Natsu whispered as the two of them went up to his room. "You lied to them."

"It worked, didn't it?" Teresa said, but this was exactly what Natsu wanted to prevent.

...

Lucy

Lucy was able to make it all the way to Natsu's house. She might have made it all the way there, but there was still the issue of getting inside. That mansion was like a fortress.

"I don't like this, Lucy." Stella said as she was against the idea.

"I've got to try and do something." Lucy said as she was determined to make sure she gets in there and stop Teresa from getting whatever she wants.

"Just please promise me you won't transform." Stella said as she knows how Lucy might think. Lucy tried to figure out how she was going to get over that wall without the use of her powers. She looked around and soon spotted something that could actually help. Using her keen mind and creativity, she spotted some things that might be able to help.

...

Natsu and Teresa

Natsu and Teresa was up in his room. Natsu had everything set to study, but Teresa was more interested in learning everything she can about Natsu so she could make him hers.

"Teresa, you didn't need to lie to Invel and Jacob the way you did." Natsu said. "You were the one that needed my help, not the other way around. Besides, if my brother find out about this, they could get into some real trouble."

"Relax, Natsu. All I did was tell them things that would help us." Teresa said as she acted like it wasn't a problem. Natsu thought differently. Teresa looked around and was fascinated with everything she saw. Even when she opened up his miniature fridge and spotted all the meat. "You sure do seem to eat a lot of meat."

"Uh..." Natsu tried to come up with some excuse without telling her about Igneel.

"Oh, this is probably why." Teresa said as she spotted a photo of him on the fencing team. "You must be getting the protein you need for your athletic body."

"Sure... Let's go with that." Natsu said. Teresa could see a lot of potential from the things Natsu has, but she did spot something she didn't like. She spotted a photo of him with Yukino, and they looked really close with each other.

"Who is this girl with the white hair?" Teresa asked.

"That's Yukino." Natsu said. "She does some modeling herself, and she's really nice. She and I actually have a lot in common." That was something Teresa didn't want to hear, but she had an idea to change all that when she spotted her phone. "Teresa, you said you needed help with some studying. We don't have a lot of time left. Maybe you should quit fooling around."

"You're right, Natsu. I already wasted enough time. I think it's best that I go, but could you do one thing before I go?" Teresa asked. "Could you unlock your phone for me? I just want to do one thing."

"Uh... Okay..." Natsu said as he just went along with it and opened up his phone. When he handed it over to her, she grabbed it and took a photo of her giving him a small kiss, trying to make it look like they were dating. When she got that photo, she sent it to all his contacts. "What did you do that for?"

"I have my reasons." Teresa said as she passed his phone back to him and showed herself out. Natsu had a bad feeling about this. That photo was sent to everyone he had in his contacts, which will result in some trouble.

...

Lucy

Lucy was still trying to get in Natsu's house. She tried stacking a bunch of trash cans over each other to climb over them.

"Sure hope it holds." Lucy said as she was hoping for the best. She tried climbing up. It was a little shaky, but she kept going. Suddenly, her phone alerted her and she saw the photo that Teresa sent. "What?!" In the shock of the sight, the trash cans ended up falling apart and took her down with it.

...

Zeref

All Zeref was really doing was staring at the portrait of his parents. However, he snapped out of it when even his phone was alerted. He looked and saw what Teresa sent and was quite shocked to see what happened in his own house without his knowledge. Wanting to get to the bottom of this, he marched right out.

"Hurry, please." Jacob said as he and Invel tried to get Teresa out of the house. She was just about out when they heard the doors to Zeref's office opening up and Jacob quickly hid Teresa behind him. They both tried acting casual, like nothing was wrong, but Zeref knew better with the look he was giving them.

"Mr. Zeref Dragneel!" Teresa called as she willing stepped out from behind Jacob and went to greet him. "It's an honor to meet you. I just want to say that I am a fan of your work and you have such an amazing brother. I'm sorry for sneaking in, but I just had see this place for myself. My name is Teresa if you want to get in touch because I would love to work for you." She said before she showed herself out and felt satisfied with what she did. Invel and Jacob felt like they were in trouble.

"Sir... I..." "In my office! Now!" Zeref ordered both of them. They were both in real trouble.

...

Teresa

Teresa was on her way out. She was passing by the corner when she spotted Lucy in the trash. It would have been the perfect chance to humiliate her.

"Nah... Too easy." Teresa said as she declined what she was being given and just walked out of there. Lucy was able to dig herself out, but she really couldn't stand Teresa.

...

Zeref

"What was this girl doing in my house without my knowledge?!" Zeref said as he wasn't pleased with either of his employees.

"She said she was here to help Natsu with his studies." Invel tried to explain.

"Is that so?" Zeref said. "Let me make some things clear for the both of you. I decide how to help my brother with his studies. No one is allowed in this house without at least me knowing about it. Also, you were suppose to check with me on a matter like this first!" Both of them felt like they were in so much trouble. "Leave me for now!" The two of them just did what he said and didn't want to get into bigger trouble. Zeref wasn't pleased with this, but he did find some use out of it. "I believe this photo could be of use. I can sense this is about to stir someone with great grief." Knowing where this might be going, he reached for the hidden switches on the portrait and went into his secret lair.

...

Yukino

Meanwhile, Yukino was in the park as she had some time to herself. She just sat in a bench at the park and did some of her own personal work in a journal. While she was working on it, she heard her phone and saw it was from Natsu. When she took a look, she was quite shocked to see the photo of him with Teresa. Yukino felt like she got shot by a bullet. She thought she and Natsu had a good connection, but seeing this photo is doing some damage to her. She flipped through the pages of her journal and pulled out a pressed rose, the same rose that Natsu gave her once. Being filled with grief, this was just who Zeref wanted.

...

Black Wizard

Zeref already transformed into Black Wizard and was ready to put his plan into action.

"I can feel a broken heart, the pain of wanting to be with someone, but there's something in the way." Black Wizard narrated. "Not everyone has the strength or will to take what they want, but I can fix that." He had an etherious fly into his hands and filled it with some dark power. "Fly, my evil etherious, and evillize her!"

...

Yukino

Yukino buried her face in her knees. She felt just so sad for she wanted to be with Natsu, but it seemed like she can't. That was when the etherious flew by and went into the pressed flower. That connected her to Black Wizard.

"Stalker, I'm Black Wizard. I'm giving you the power to hunt down your target, no matter how far they go. No one will ever be able to escape from you. In exchange, you must bring me the miraculous of Celestria and Salamondra. What do you say?"

"I'm in. They won't know what hits them." Yukino said as she accepted the deal and transformed.

...

Natsu

"Why do you continue to hang around that girl when you know she's just a liar?" Igneel questioned.

"She's probably just looking to be less lonely." Natsu said as he wants to see the good in her. He knows what it's like not having people around.

"That should be her punishment for constantly lying." Igneel claimed as he wasn't as nice. "Natsu, if you continue with this, you're just encouraging her to keep lying to people. She's got to learn she can't do that. Until she does, it might be best you just stay away from her." Natsu doesn't like that Teresa's lying, but can he really do something like that.

"Natsu..." An eerie voice could be heard. Thinking fast, Igneel hid and hoped he couldn't be seen. When Natsu turned around, he saw Stalker standing at his window. She was wearing an all white suit with red horns coming out of her shoulders with a rose having a horn as a symbol on her chest. Her face was also painted snowy white with a horn coming out of her head. The pressed rose she had also turned into a sword.

"Yukino?!" Natsu said as he was shocked to see her like that.

"Tell me about the girl in the photo. Is she your actual girlfriend?" Stalker said.

"You mean Teresa? No. She just looks for attention." Natsu tried to explain.

"If so, I know what to do." Stalker said and dived right out of there. Natsu didn't like the looks of this at all.

"I knew with all these girls, there would be trouble." Igneel said.

"I don't know what you're talking about, but there is no time." Natsu claimed as he got to work. "Igneel, Fire Up!" He became Salamondra and hurried after Stalker. As for Lucy, she cleaned up the mess, but she did spot Stalker running off and knew there was trouble.

"Can I transform now?" Lucy asked.

"Of course." Stella said.

"Stella, Twinkle!" Lucy became Celestria and hurried after Stalker. The hunt was on, and the target was Teresa.

...

Teresa

Teresa was on her phone and was just minding her own business, feeling satisfied on what she has done. What she didn't know yet was that Stalker was hunting her down...and already found her. She crept around every corner and shadow. Teresa soon got the feeling that she was being followed. Without warning, Stalker appeared in front of her and gave her a good scare.

"Hello, Teresa." Stalker said as she held up her weapon to her forehead and caused a faint light to shine. "I'm giving you the chance to back away from Natsu and never go near him again."

"What?" Teresa said.

"Sorry, but he doesn't belong to either of you!" Celestria showed up right in the nick of time as she pushed Teresa out of the way and tried getting her out of there.

"All this trouble over a guy? You girls should no better." Salamondra said as he stepped forward to challenge Stalker. Stalker took the challenge as she charged right at him. As for Celestria, she tried to get Teresa out of there, but she was less than coorapertive.

"I don't need your help, Celestria!" Teresa said as she pulled her arm free. "I can take care of myself without your help." She clearly still holds disdain for Celestria over what happened before.

"Teresa, I get you don't like me, but I still need to make sure you're protected." Celestria said.

"As if you could do anything right. Besides, a girl like that doesn't have a chance with Natsu." Teresa said.

"And you think you do?" Celestria mocked. Before they could argue more about it, Salamondra was thrown near them and Stalker came closer to them. Celestria pulled out her whip and tried to grab her, but Stalker knocked it away with her weapon. While they were fighting, Teresa tried running for it.

"You can't hide from me, Teresa. I will hunt you down." Stalker warned.

"You'll have to get through us first. Although I'm not sure why we should protect her." Celestria complained.

"Come on. She's still a defenseless girl, and might warm up to you eventually." Salamondra said. The two of them tried charging at her with their weapons, but Stalker jumped right over the both of them. She knocked her weapon against both of them and pushed them down. They could be in trouble with this villain.

...

Teresa

Teresa was running for her life, trying to get as far from the villain as she could. When she saw Officer Lahar in his car, she saw a chance to escape.

"Officer!" Teresa called and got him to pull over. "Please help me. A supervillain is after me and Celestria is failing to protect me. You need to get out of here."

"Hop in. I'll get you somewhere safe." Lahar said. Teresa helped herself as she got in the car and started to drive out of there while the two heroes did their best to hold off the villain. However, Stalker had something sneaky in plan.

...

Stalker

Stalker was capable of holding her own against both heroes, but she stayed focused on her goal: Teresa. When Celestria threw her whip at her again, it coiled around Stalker's blade, but Stalker pulled her in only to kick her back.

"I'm starting to think the etherious is in that strange blade of hers." Celestria said.

"But she's quick on her feet. Any ideas as to how we're going to grab it?" Salamondra questioned.

"You'll have to catch me first." Stalker said as her idea was about to come into action.

...

Teresa

"Maybe I should take you to the hospital for your forehead." Lahar said as he noticed something.

"What about my forehead?" Teresa said. That was when she looked in a mirror and saw a red horn growing out of her head. "What the heck?! What is this thing growing out of my head?!" Teresa had no idea how she got a horn coming out of her head. To add to the strangeness, Lahar received a message on his phone, but there was a strange symbol on it. The same symbol Stalker wears.

"What is this?" Lahar questioned before he was enveloped in a bright light. Teresa had to shield her eyes, but was in for some horror. When the light faded away, she panicked when she saw Stalker was there instead of Lahar. She dived out of the car and tried to run for it, but Stalker didn't bother chasing after her. The reason is because there's nowhere she could hide that Stalker can't find her.

...

The Heroes

The two heroes were ready for another round against Stalker, but they didn't get the chance. Stalker mysteriously just disappeared and Lahar was in her place.

"Officer Lahar? What are you doing here?" Celestria questioned.

"I... I don't know. I was helping this poor girl with a horn when I got this strange message on my phone." Lahar explained. "When that happened, I found myself here." Neither of them understood what that meant, but they still needed to get Stalker. Lahar told them where his car was left and hurried to where it was. Once they got there, they spotted Stalker was still in the car. Celestria acted fast and wrapped her whip around the car to keep her trapped. However, Stalker didn't seem worried since she had a smile on her face.

"Why is she smiling like that?" Salamondra questioned.

"Careful. This one seems tricky." Celestria said as she knew something was off.

...

Teresa

"Help me! Someone help me!" Teresa called as she ran into the first building she could. Conveniently, she ended up running in the Heartfilia Bakery.

"Oh my! Your forehead!" Layla pointed out. That was right when her phone alerted her of a message, the same message Lahar got. When she saw it, she disappeared in a flash and switched places with Stalker. Now Stalker was in the bakery while Layla was in the cop car with the two heroes surprised. Teresa tried running out of there. Stalker was about to go after her, but Jude bravely stepped in the way.

"Hold on. What did you do with my wife?" Jude questioned, demanding for answers. While Jude was foolishly trying to handle the villain, Teresa tried running for her life. That was right when the two heroes showed up.

"Teresa, are you okay?" Celestria asked.

"Celestria! I'm so glad to see you!" Teresa claimed as she hugged her, but it was a lie as the horn grew bigger, and she knew what would happen next.

"See. I knew she always liked you." Salamondra said. That was right when Celestria got the same strange message. When she took a look at it, she disappeared and stalker appeared in her place. "Hey! The girls were just getting along!" He complained and tried to fight off the villain while Teresa ran off.

"Give up on Natsu!" Stalker called.

"And let you get your creepy claws on him? No way." Teresa refused. While Salamondra was trying to fight off the villain, Celestria was in the bakery and confused as to how she got there. When she looked around, she spotted her father on the ground. Hurrying over to him, she helped him stand.

"Celestria? Where's my wife?" Jude questioned.

"She's safe, but can you tell me what happened?" Celestria asked.

"I'm not sure. My wife got this strange message, next thing I knew was that she was gone and that villain went after that girl." Jude explained. Celestria tried putting the pieces together and might have something.

"That horn on Teresa must be how Stalker keeps finding her. She somehow sends messages that allows her to switch places with whoever is with Teresa." Celestria said. Now that she knows what's going on, she can come up with a plan on countering it. As for Salamondra, he kept trying to fight off Stalker and prevent her from leaving.

"You won't stop me. She doesn't deserve Natsu." Stalker said.

"Oh please. He can't be all that." Salamondra joked.

"Don't insult, Natsu! He is amazing, and someone who I might love!" Stalker said.

"Wait. What?" Salamondra questioned as he wasn't expecting that, but Stalker smashed her foot against him and knocked him down. Once he was out of the way, she chased after Teresa again.

"I see you had that handled." Celestria sarcastically said as she went to him and helped him up.

"She...caught me off guard." Salamondra said.

"Well, now I know how she's tracking Teresa. We need to get moving fast." Celestria said as they chased after her.

...

Teresa

Teresa just kept on running, trying to get as far from Stalker as she could, but it was no use because of Stalker's ability. Teresa kept running until Stalker appeared right in front of her and pushed her to the ground.

"There's no use in running. Just give up on Natsu and I'll leave you alone." Stalker offered.

"Okay. You win." Teresa agreed and sounded sincere, but Stalker knew it was another lie when she saw the horn on her head grow again.

"You're quite the actress, but that horn betrays you. It reveals when you lie." Stalker claimed. "If you won't stay away from him, I'll make you." She threatened as she looked ready to attack her.

"Wait! What if we made a deal?!" Teresa desperately offered.

"What could I have that you want?" Stalker questioned.

"I'll stay away from Natsu...if you get rid of Celestria." Teresa proposed and really meant it. Stalker was suppose to do that either way, but Black Wizard was amazed that Teresa would make such an offer.

"Teresa!" Celestria called as she and Salamondra were able to find them.

"Consider it done." Stalker said as she accepted the deal. She charged right at the two heroes and tried to fight them off like she was suppose to. This was going just how Teresa and Black Wizard wanted, and Teresa intends to help with it.

"Salamondra, help! It's my ankle!" Teresa called as she acted like her ankle was hurting.

"I got you!" Salamondra said as he hurried to her.

"Are you serious? What if she's lying?" Celestria said as she was trying to avoid Stalker's weapon.

"She wouldn't do that now. I'll be back." Salamondra said as he lifted her up and took off, but it was just what Teresa wanted. Celestria was forced to fight Stalker alone now. Salamondra carried Teresa away until he spotted an ambulance with a paramedic in it. He jumped right in the way to make sure he stopped. Meanwhile, Celestria kept dodging Stalker's attacks. Once she jumped away, she decided to end this now.

"Open the Celestial Gate!" Celestria used her powers and ended up getting a Pisces hose, but Stalker jumped over and grabbed it before she could. Once Stalker did that, she moved incredibly fast and tied Celestria to a light post with the hose.

"Nowhere to go now, Celestria." Stalker claimed as she had her trapped now.

...

Salamondra

Once Salamondra got a paramedic, he was able to look at Teresa's ankle.

"Are you sure about this?" The paramedic asked.

"Of course I'm sure. She said her ankle hurt." Salamondra said. Salamondra was ready to go, but needed to make sure Teresa would be safe. The paramedic's phone did went off, but Salamondra knew it was dangerous. "Don't answer it!"

"But what if it's an emergency?!" The paramedic asked.

"Someone else can handle it. Focus on her ankle." Salamondra said.

"Are you sure you don't want me to look at her head because her ankle is perfectly fine." The paramedic claimed. When he said that, Teresa's lie was caught and Salamondra was astonished at what he has heard.

"Teresa? You lied?" Salamondra questioned, but Teresa didn't see a way out of this. "You just wanted me away from Celestria, alone with the villain?! You hate her that much?!" Teresa unable to answer proved to Salamondra he was right. He is now starting to see what a horrible person Teresa really is. "Answer the phone." The paramedic did what Salamondra said. He answered his phone and the timing was perfect. Stalker was just about to take Celestria's earrings, but she and the paramedic ended up switching places.

"What happened?!" Stalker questioned.

"A change of dance partners." Salamondra said as he pulled out his staff and was ready to fight.

...

Celestria

"Celestria? How did you get tied up like that?" The paramedic asked as he worked to untie her. "These hoses are a hassle to untie. A poor kid got tangled in them and it took us nearly two hours to get him free."

"Really?" Celestria said as that might have given her an idea to catch this villain.

...

The Fight

Stalker and Salamondra kept on clashing their weapons against each other. The two of them kept going at each other until Celestria called Salamondra.

"Excuse me. I probably have to take this." Salamondra said. He kicked Stalker back and took the call. "Yeah? Got it." Celestria filled him on the plan. Once he got it, he grabbed a hold of Teresa and retreated, trying to get as far from Stalker as he could as fast he could.

...

Celestria

Celestria remained tied for her plan to work. When she saw Salamondra and Teresa show up, she knew it was about to happen. They landed down near her and got herself ready. Stalker followed after them, but Celestria's whip was alerting her of Stalker's message. When Stalker arrived, it was too late. Celestria answered the message and it caused her and Stalker to switch places. Now she was free and Stalker was the one that was tied.

"Dragon Fire!" Salamondra used his powers and turned it to ashes and caused the etherious to fly out.

"No more evildoing for you, little etherious." Celestria activated her whip and began twirling. "Time to de-evillize!" She tossed the whip and was able to catch the etherious. "Gotcha! Bye-Bye, little guy." Once she purified and released it, Celestria was able to get a hold of the hose. "Miraculous Starlight!" She tossed it up in the air and unleashed the magic stars that fixed everything like Teresa not having a horn anymore. Stalker also turned back to Yukino with her weapon turning back into the rose.

"What happened to me?" Yukino questioned. Celestria held up her fist for the celebratory pound, but Salamondra focused more on Yukino. He reached down and grabbed a hold of the flower.

"I believe this is yours." Salamondra said as he handed her the flower. Yukino took it back with Salamondra lifting her up like a princess. "I'll take her home. Watch out for Teresa, lying is like breathing to her." He warned Celestria before he took off.

"Your ankle certainly looks better." Celestria told Teresa, but Teresa was always ready for an act.

"I guess it was those magical stars." Teresa lied.

"So, you don't have a problem walking home." Celestria said as she just took off and left Teresa alone.

...

Black Wizard

"You may have won this time, but it looks like I might have a new acquaintance. Someone who hates and despises you as much as I do." Black Wizard claimed as he sees someone he can use.

...

The Next Day

"Natsu, I could still use your help. Can I come by your place again?" Teresa asked as she tried making another attempt at him, but Levy was surprised when she saw Lucy just ignored what happened.

"You're not going to follow them again?" Levy asked as they headed for the exit.

"No need to. I trust Natsu, Levy, and there's no way he would ever get involved with someone like her." Lucy claimed without Levy really knowing what she meant.

"Sorry, Teresa. I can't because I got fencing." Natsu said as he and Teresa were on their way out as well. "Besides, I'm not going to be part of your little game." He wasn't going to be fooled by Teresa again. "Invel and Jacob got into trouble because of you. I'm not going to be a part of that."

"I'm sorry, Natsu. I didn't mean to." Teresa claimed.

"I want to believe you're a good person, Teresa, but until you learn to be a decent person, just stay away from me." Natsu declared as he wasn't going to get involved with Teresa and her lies again. Good for him, not good for Teresa. However, he might not have much of an option. Teresa got a call from her phone, but had no idea who it was. She still went on ahead and answered it.

...

Zeref

That person that called Teresa was actually Zeref. He willingly invited her over. Teresa couldn't believe it, but she did feel like she was in actual trouble with him.

"You lied to my staff, Miss Teresa, in order to infiltrate my house and get closer to my brother." Zeref said.

"I'm really sorry, Mr. Zeref Dragneel. It's just that I'm a fan of yours and Natsu that I just couldn't resist." Teresa said. "I swear I had every intention to get close and help Natsu. I can't imagine how he feels when he feels trapped here. He just wants some friends."

"I should be displeased, but I'm actually impressed." Zeref said. "It would seem like you would go to great lengths for my brother. I do the same. I believe we might be able to help each other. You help me, I help you. I believe I might have some use for someone like you. What do you say?" He asked as he held out his hand for an agreement. Teresa saw this as another opportunity as she gladly took his hand, not aware that she'll also be helping Black Wizard in the process. Even if she did know, she would still do it.
