Who killed Matt

Who dunit

"I'd like to say a few words for our fallen hero; Zero. Hey was decent man-" a political figure is shouting from the park down below. Let's not focus on the funeral down there. Let's focus on me, Matt. On top of building a yard away, watching it go down.
"So...you're dead." Draculeta asks, her fingers curling around mine. I return the favor, I feel her fingers through my gloves.
"I mean, yeah, someone tried to kill me. So I'm abusing the opportunity to go looking for them. As long as everyone believes I'm dead, it might make it easier to look for them."
"I think I get it. I wouldn't think it was a good idea. Heroes have the support of the police. They could be looking instead." She says sounding a little upset.
"The police are too used to the supervillains and stuff being easy once they're beaten. They'll be too loud for this." I reply.
"You're going to be busy with your investigation." She groans. They specifically tried to kill me, after some other murders. I have to know who dunit!" I say.
"You wanted to say that." She says, I nod in agreement.
"You gotta give me some time to find them."
"What do I do in the meantime?"
"What you always do when I'm not around."
"Tsk, fine. I'll look for something to do."
"You say that like you never have something to do. I've seen your room." She gives me a light shove. Though, her idea of a light shove almost threw me off the roof. I finally pull myself back into position. "Go home and study or something." I add.
"I am almost done the semester."
"Of course you are." I say that remember I'm just keeping up with my classes. After this, I really gotta go back to studying for my classes.
"You're gonna have trouble pretending you're dead in front of your mom." She adds.
"I...i got that.... maybe." I say awkwardly.
"Wanna stay at my place?" I blush  heavily at the suggestion.
"I uh, don't want to impose on you."
"We've rutted like animals, you've seen me naked AND in my pj's and underwear, AND you've slept over a few times. Is living with me that hard?" She complains.
"Maybe."
"You have commitment issues."
"What?! I so do not!" She has me shouting on this rooftop.
"Prove it. Start committing to this relationship."
"I-fine I'll do it. Only to hide from everyone that knows me."
"You better start liking the idea of us being together!"
"Okay, okay. Please calm down before someone find out that we're up here and they'll know Zero isn't dead." I say trying to calm her down.
"That has never worked on a woman. And take your mask off then." She replies, taking her thumbs sliding them into my mask and pulling it off my head, the goggles popping off with. "There, now you're Matthew. Nikia's boyfriend."
"Take off your makeup and put on your glasses, then you're Nikia. Matthew girlfriend." I add.
"Am I not now?" She asks worried.
"Right now, you're Draculeta. Zero's friend....with benefits." I whisper the last part.
"Uhuh, I've 'gotten along' with 'Zero' for a year and a few months now."
"Yeah yeah, you've been a good girl up until now."
"....save that for later." She mutters. I blush realizing what I said.
"For now I just have do two things, school, and figure out who wanted to kill me." I explain.
"I will be there if you assistance. Both at home and in the field."
"Thank you very much, Niki."
"So you use that nickname too?"
"Yeeeeah." She sigh and lays her head on my shoulder.
"Don't make it a habit." I lay mine head on hers.
"I understand." I add.
