Halloween was right around the corner. The kids were not allowed to wear costumes to school, but there were always wild costume parties thrown at night. The most notorious of them all were the Mike Chang parties. This year was going to be the first year that the Glee Kids were invited to such an event. There was this small shop at the edge of town that had the best costume and prop selection so there were always huge lines of people waiting to put in their custom costume orders.

Finn held onto Mercedes' hand with a tight grip as he led her around the various aisles.

"Come on, come on, there has to be at least one." The lengthy teen's eyes darted around the aisles looking for a very specific costume.

"What's the big deal Finn, it's just Halloween, they have one every year." Mercedes was getting a tad embarrassed watching her boyfriend act like a 6 year old.

"But I love Halloween. And I want a good Robin costume but I don't think they have one in my size."

"Why do you want to be Robin?" Mercedes understood Finn's fascination with superheroes but she couldn't understand why he would want to be the sidekick.

"Umm…cause he's awesome." Finn looked at his girlfriend like she had just asked a ridiculously stupid question.

"Why don't you be batman? Look, they probably have adult batman costumes at the other end of the store."

"But Batman can't be a teen titan Mercedes, he's too old." Finn looked sad at the possibility of not getting to be his favorite hero for Halloween.

"I don't know how you manage to make dorky things sound so cute."

Mercedes took Finn's hand and led him to the other end of the store. As they turned the corner to the adult section, Mercedes spotted Santana at the other end of the aisle picking up an adult Cat Woman costume. Both she and Finn waved, but Santana just scowled and walked away with her nose stuck firmly in the air.

"What's her problem?" Mercedes questioned.

"I don't know." Finn did not tell his Mercedes that he had slept with Santana. It didn't mean anything to him so he didn't feel like it was worth mentioning. Also, he noticed how Mercedes and Santana were always gunning for each other and were hyper competitive so he decided to not add any more fuel to the flames.

"Hey, I almost forgot that you need a costume too Mercedes. "

"Oh, I was thinking about going as Diana Ross or something; someone with a lot of soul. "

"Just get something from here; you have the money for it."

"I can't get anything from here Finn. These costumes aren't very…me"

"Why not? Is this one of those "not wanting to show up in the same outfit as another girl" things."

"Show up…what do you mean show up? I thought we were just going trick or treating with Artie and Tina."

"Didn't I tell you about Mike's Halloween party? Everyone from the club is going."

Mercedes was not used to the Lima dating scene. So the little details like showing up to parties together were still big surprises to her.

"Finn I don't want to go, can't we just ask strangers for candy."

"It will be fun; we'll have a great time I promise. You laughed really hard when I showed you the face book photos from last year's party, imagine how much more fun it will be when you're actually there. Now come on, pick out a costume."

"Finn none of the stupid costumes in this stupid store will freaking fit me OK."

Mercedes cast her eyes to the floor in shame. Finn wrapped his arms around her and rested his chin on top of her head.

"It's OK, we can go as other stuff. I don't have to be Robin." He said reassuringly as he gently rubbed her back.

"It's not OK, I saw how your eyes focused on San's tight little ass like a hawk as she walked away." Mercedes let out a soft whimper that sounded almost like crying.

Finn tightened his grasp to prove to his girlfriend that he was not going anywhere.

"I was not (he was). And San's crazy (she is). What would I want with that drama?"

"But I'm kinda crazy too. I got a diva attitude and I can be bossy as hell just like Santana but I can't fit into the Cat Woman suit, so what's in it for you?"

Finn kissed the top of her head and pulled back so she could see his face.

"But I like you're type of crazy. You're type of crazy is protective and supportive. I kind of feel invincible when I'm with you, like I can do almost anything, hence the superhero theme this year."

"Finn I care for you I really do. But if you're staying with me just to be nice…then I think we should just end it now."

"Is that what you want?" Finn's voice was shaky at best.

"Of course not! But Mike's party would be our first real high school party as an official couple. I don't want to face all the judgmental glares from other people if you're going to leave me at the end of the night for some skinny slut dressed like Starfire."

"Mercedes, how many more times am I going to have to tell you that my feelings for you are real before you believe me? This relationship means something to me. No slut dressed like Starfire is going to steal me away from you because you are my Starfire."
