After Marco rejected Star's invitation, he starts to envision someone from his past, someone that is haunting him.

Marco was in his room trying to calm down his arm, as it was flailing around trying to find something to break, Marco pulled out a needle and shoved it in his arm calming it down, giving Marco control again, he then turned it back into a standard arm and sighed.

"Just a little longer, please let me control it for a bit longer." He said to himself in a whisper, just then he heard a knock on his door.

"Marco, you in there?" Star asked

"Yeah, i'm in here." He said

"Can I come in?" She asked.

"Not now, I need to be alone." He said.

"Well, I just wanted to tell you goodnight." She said

"Yeah, goodnight." He said.

"Aww all she wants to see you, and you can't let her have that?" Jackie asked, Marco just ignored her. "Not talking to me huh? Even though you called out my name not too long ago." She said Marco then swung his arm to hit nothing.

The Next Day

Marco was at school doing his own thing while keeping his distance from people that's when Star came and grabbed him.

"Marco come have lunch with me." She said

"Uh, Star I don't think…" "Oh look at the two monsters." The two then looked up and saw Brittany Wong and her entourage.

"What do you want wrong?" Marco asked

"I was just wondering how our school pets are doing and making sure that you got fed." Brittany said as she pulled out a cup of crickets and tossed it at Star opening on her dress. "Oh can't forget you, Diaz." She said as she grabbed a can sardines and threw them on him. "Enjoy you freaks." Brittany said as they started laughing and walking away. Marco then sighed and cleaned himself up.

"Man, they don't have anything better to do than to mess with us?" Marco asked he then looked over and saw Star taking a few short breaths.

"Yeah, they must have a lot of free time." She said, Marco then looked at her worriedly, he knows how she felt and was trying to make her feel that way.

"Hey let's get some real food." He said as they went to the cafeteria and immediately they got stares, just a typical day as it came to an end Marco and Star were once again met with Brittany Wong.

"What is it now." Marco asked

"Listen I want to apologise for the way I so I got you two something." She said as she handed them a box, Star opened it to reveal more bugs mixed with chum.

"A gift for all monsters." She said as she started laughing soon everyone around them started laughing at them, Marco was used to it, but Star reached her limit, she then grabbed Brittany by her arm and looked at her with a smile.

"You know Mrs. Wong I was taught on Mewni never to let mewman or any one talk or treat me in such a disgusting manner." Star said as she started to tighten her grip. "But we're not on Mewni!" Star's pupils then turn into slits, and her claws were digging into the pampered brat's arm.

"O-okay, you made your point, you c-can let go now." Brittany said trying to get free, Star then grabbed her shirt collar and tossed her on her back with a lot of force, she then stood over her and grabbed her neck and lifted her up.

"I already take a lot of crap from my aunts and uncles; i'm not going to let some lower-class species talk down to me!" Star said as she tightens her grip crushing her windpipe. Brittany was now struggling; her face started to turn red, everyone watch in fear, Star just smiled as held her, Star almost killed the pampered bitch, till Marco step in, he forced Star to let go of her and held her back.

"Star calms down; she's not worth it!" Marco said

"Why not! Everyone lives would be much better if she were gone!" Star yelled at him.

"Because people will never let it go! You'll constantly be reminded and haunted by this person until you die!" Marco said, Star then looked at Marco who had a worried look. "Don't make the same mistake I did." He begged, Star's eyes turned back to normal, and she then started to cry, Marco then pulled her into an embrace.

"It's okay let's just go home for now," Marco said as they began making their way back home.

Later that night

Marco was in his room thinking about today till he got up and went to Star's door, he knocked on said door, it soon opened to reveal the princess.

"Marco?" She asked

"Star, can we talk?" He asked, Star then lets him in and Marco sat on her bed, and she sat next to him.

"If it's about today, I don't want to talk about it." She said.

"No, that not it, I wanted to tell you about someone I held close, but I ended up making a mistake that I regret to this day."

Flashback (Marco's P.O.V)

This was back before anyone knew about this damn arm, I was walking to school minding my own business when she came up to me."

"Hey, Diaz!" I looked back to see Jackie Lynn Thomas, back then she was the first girl I ever loved, but I was just too scared to do or tell her anything. As she approaches me, I could feel my heart racing.

"Hey Jackie, what's up?" I asked as my voice cracked

"Hey, I was wondering if you wanted to hang out tonight." When she said those words, my heart skipped a beat.

"Sure!" I said way too excitedly, which made her laugh a bit, but I didn't care I had a date with Jackie, but what happened next was all just a blur. Jackie was taking me through the woods till we found you near a cabin it was a small and so far away that no one was around as we entered the cabin. Jackie started to get undress, making me nervous, she looked at me and expected me to get undress as well, as I took off my shirt, I got this strange feeling I looked around and saw something in the window, I went over to and saw what looks like a camera.

"Uh Jackie, what this?" He asked, Marco looked back and saw that Jackie was gone. "uh Jackie?" I kept calling her name, but I got no response I then went outside only to have a bright light shine on my face. As I got used to it, I saw others classmates with various blunt objects.

"Uh, what's going on?" I asked, trying to look for Jackie. They all told me that they were here to kill me, they said hurtful words, making me angry as soon as they charged towards. My arm took control and started attacking everyone, and all I did was smile as if they wanted a monster then they got one as soon as they all laid on the floor all groaning in pain. That's when it happened, Jackie was rushing towards me holding a knife, and all I did was smile as my arm, MY arm impaled her chest sending her heart flying to a tree as she looked at me with an angry expression as she went limp.

Flashback end

"Ever since then I've been labelled a monster, the entire town knows about this arm, the only reason I wasn't-convicted was that I was defending myself, but I still see and hear her." Marco then began to cry. "She haunts me, constantly reminding me, that I am a monster. I don't want you to make the same mistake that I did." He sobbed, Star then pulled him in for a hug and for once he accepted it from her as he cried on her shoulder.

"I just want it to end." Marco said as Star patted his back.

"Don't worry Marco; it'll be okay." She said

"It won't not until I make up for my mistake." He said as he let's go.

"Marco, promise me that you won't do anything stupid." Star asked, Marco didn't give her a straight answer, he just turned to her and smiled

"Good Night, Star." Marco then left the room leaving Star worried about him.

"Aww, that's so nice you finally admitted you killed me, so what's next?" Jackie asked

"Shut up! Just leave me alone!" He gritted.

"You know what you have to do, to get rid of me Marco." She whispered in his ear, Marco then looked at his arm and grabbed it.

"I know, just please give me more time." He said as he entered his room.

The Next Morning

Star awoke to the shine of the sun, recalling last night conversation she got up and went to Marco's room and knocked on the door.

"Marco are you up?" She asked but got no response. "Look, I know that I can't go to school today, but I was wondering if you want to hang out?" She asked, but got no response, Star then took a deep breath and entered the room only to find him gone.

"I guess he went to school." She said, Star then sighed and left back to her room, Star then went back to her room and laid down on her bed.

"I wonder what Marco meant by paying for his mistakes?" Star thought. She then got up and walked to her mirror and called her father.

"Hello Star, what are you doing shouldn't you be at school?" Toffee asked.

"Sorry, but something happened." She said filled with guilt "But that's not what I'm calling, I wanted to know what does someone mean when they say "I have to pay for my mistakes?" She asked

"Well, it often implies that said person is repaying a favour or…" Toffee then went silent. "Star, where's your friend?" He asked

"I don't know I went to check on him, but he was gone." She said

"Okay, Star listens to me, you need to inform you caretakers and go look for him!" He said. Star then obeyed her father without a second thought. After she did the family started to look for Marco all over town it took them hours but had no luck finding him.

"C'mon Marco, where are you!" She asked herself that's when she remembered his story, Star then hurried towards the woods she looked all over and turned up nothing.

"MARCO! WHERE ARE YOU!" Star called out as she started to tear up.

Meanwhile

Marco was standing in front a hand-made grave with a piece of wood sticking out.

"So after all this time you finally come to visit me? I hope you at least brought me a gift?" Jackie asked

"Don't worry you'll get what you want." Marco said as he started digging up the grave he soon stared down at the carcass below. Marco then grabbed then the body and took it near a fire pit.

"With this, I get rid of everything that forever haunts me." Marco then grabbed some wood and started a fire. Marco then tossed the carcass into the fire watching it turn into ash.

"Please forgive me for what I did." He said

"Almost, now it's your turn to join me." Jackie said, Marco then took off his hoodie and shirt. He then grabbed a knife and pointed it at his heart. "That's it end it you monster, make amends by finally killing yourself!" Jackie repeated in his ear, Marco then raised the knife and stabbed his heart, He stumbled back as his vision started to blur, he stumbled for a bit before falling back. Tears filled his eyes as turned his head to the side; he then saw someone ran up to him, as the person got closer, Marco's vision went black.
