Jen woke the next morning, only to realize the whole house started shaking. She looked out the window and noticed none of the other buildings were being effected. She ran into the safety room. "Sarah, would you calm down? You're shaking the entire building!"
"Sorry." Sarah said.
"What happened?" Jen asked.
"When I woke up, there was this moth in my hair." Sarah told her. Jen looked on the side and saw Sarah's little 'moth' on the floor.
"Is this what you're talking about?" Jen asked. "Sorry about that. I told Mini Chill not to be going off around the house. By the way, how's the injury?"
"Better, thanks to your help." Sarah said.
"I'll meet you at the park this afternoon." Jen said. "There's a back way out of this room."
"Thanks, Jen." Sarah told her. "I'll see you later."
When Jen got to the park, she saw Allison talking to her boyfriend. "Hey, Jen." She turned around to see Francesca.
"Hey, Francesca." Jen said. "It's great to see you again."
"It's nice to see you, too. How's you're friend, Aaron?"
"He's doing well. Our little team is growing even more."
"Ali's been telling everyone." Francesca said.
"She's on our side now." Allison was saying as Jen came over. "Oh, hi Jen."
"Allison, we need to talk." Jen said.
"Look, I don't like the fact that Sarah's around." Allison told her. "Even though she saved us, I still don't like her. It feels like she's replacing me."
"Allison, are you crazy? You'll always be my best friend." Jen said.
"Besides, nobody could replace you." Frank said. Allison blushed. All of a sudden, two hoverboards nearly flew into her.
"Look out!" A voice called. They all got out of the way. Aaron got off his board. "Sorry about that, sis."
"Aaron, would you please watch where you're going?" Jen asked. She turned to the other boarder, only to realize it was… "Matt?"
"Hey, Jen. Aaron was trying to teach me how to use these boards." Matt explained. "It's a lot harder than it looks. I should probably stick to motorcycles."
"Aaron, good to see you again." Francesca said.
"Oh, hey Francesca." Aaron said.
"Anyway, I understand that some of us are having issues about Sarah joining the team." Jen told everyone. "All that we know about her is that she's a Plumber's daughter who was taken in by two sorceresses after they died."
"And we only know one of them so far." Allison pointed out.
"Look, all she knows is she's originally from this dimension." Jen said. "We have to help her. Either you're with us, or we're not." Everyone was silent for a few minutes.
"I'm in." Matt said. "What about you, Frank?"
"Why not?" He said.
"If any friend of yours in trouble, you can count on me." Francesca said.
"Thanks, guys." Jen said. "Now let's try to help her feel in place."
"And find a way to convince my friend that things aren't as they seem." Sarah said, coming in from the back of the group.
"You're that girl with the CDs?" Matt asked.
"Yes, and I'm very worried about Ivory." Sarah said.
"Don't worry, we'll help you." Jen told her. Suddenly, Sarah felt something strange. "What is it?"
"I just picked up on a powerful signal." Sarah said.
"I feel it, too." Allison said. "You guys try to find out who that other sorceress is. The rest of us will deal with whoever's around here." Francesca, Tony, and Frank headed one way. Jen, Sarah, and Aaron followed Allison.
Sarah stopped suddenly, realizing that it could only be the one person. "Sarah? What's wrong?" Jen asked.
"It's Ivory." Sarah said. "I can just feel it."
"I have an idea. Just trust me." Jen said.
Sarah entered an alley by herself. She's already changed into her battle outfit. The others were hiding behind boxes. She saw Ivory in there. "Ivory." She said. The girl turned around.
"Sonica. I've been looking everywhere for you. You were taking so long to get back." Ivory said.
"I'm not going back." Sarah told her.
"Why not?"
"Because I don't belong in your dimension." Sarah explained. "And don't call me Sonica anymore. It's Sarah now."
"You've changed." Ivory realized. "You've joined those pathetic humans."
"When I came here, I remembered who I was, Ivory." Sarah said. "And there's nothing wrong with this dimension."
"To think I could trust you when you were really working with the enemy all along." Ivory said.
"Ivory!" Ivory shot a pink beam at her.
"Don't talk to me, traitor!" Ivory yelled at her. Sarah launched her disks at her. She didn't want to fight Ivory, but she wasn't giving her a choice. At some point, she ended up against a wall.
"Ivory, listen to me!" Sarah said. "You're going about this all wrong. I want to help you. You don't have to listen to her. Please."
"I'm sorry, but I can't believe anything you say anymore." Ivory said. For a moment, Sarah saw that she was really upset.
"Ivory…"
"Put her down!" Ivory turned around and saw Jen.
"What will you do if I don't?" Jen pressed down on the Omnitrix and transformed into Electra.
"I don't think you want to mess with me now." Ivory let go of Sarah and focused her attention on Jen. Sarah just watched from where she was sitting. Ivory fired at her, but Electra avoided the blasts. Allison walked over to Sarah while Aaron went out to help Jen.
"Hey, up here!" Aaron slammed into Ivory, knocking her down. "I wouldn't be attacking her if I were you."
"Sarah." Allison said. "You have to help Ivory. Try using you're song to heal her."
"I've never done that before." Sarah said. "But, if it's to help Ivory…" Electra hit the ground, unable to move.
"I've got you now!" Ivory said. Before she could strike, two ribbons were wrapped around her arms.
"Leave my friend alone!" Allison said.
"Ali, don't!" Jen said, changing back to normal.
"Interesting. You can use energy as a weapon." Ivory observed. She broke free and Allison fell back. She came over to her and grabbed her. "That can only mean one thing. You're…"
"Drop her, Ivory!" Sarah said.
"What are you going to do if I don't?" Ivory asked, throwing her to the ground.
"Nobody messes with my friends and gets away with it." Sarah said, pulling out her microphone. Jen and Aaron got out of the way, carrying Allison since she'd passed out. Sarah started singing and managed to knock Ivory out for a few seconds.
"Whoa." Allison said. "You think it worked?"
"Ivory…" Sarah said, walking over to her. "It doesn't have to be this way."
"I just can't do it, Sarah." Ivory said. "Now that you're one of them. Next time we meet, don't expect me to welcome you." She disappeared in a pink light.
"Ivory…" Sarah said. She felt a hand on her shoulder.
"Don't worry," Jen said. "We'll find a way to convince her that she's wrong." She turned to Allison. "Way to go, Ali. You revealed your power to the enemy."
"What's the big deal?"
"The big deal is that if she can manipulate energy like you can, then I know who she's taking orders from." Jen said. "Sarah, why don't you tell us all what you've been hiding." Sarah looked shocked and hurt.
In the other dimension, Ivory approached her leader. "Explain yourself." She said.
"I'm afraid that Sarah's on their side now." Ivory said.
"Big deal, she wasn't much help to begin with." The woman said.
"But I did find something else. One of the girls that I fought could use energy attacks. Like us." Ivory told her.
"What did she look like?"
"She had red hair and blue eyes."
"I see…" The woman said. "So this girl is Gwen Tennyson's daughter. This is perfect. We can use her to find Gwen and capture her."
"But what about her friends?"
"Just take them out. This time, we'll finally be able to capture Gwen."
"I understand. I promise, I won't let you down, Charmcaster." Ivory said.
