So Matt is... done. He's isolated and enstranged from his friends. He's (maybe) injured or seriously sick. Hell's Kitchen is suffering around him, and he can't help, can't work, can't do anything right... People are right to leave him. He's not helping; he's toxic.

And Matt knows his city like the back of his hand, so he knows the perfect suicide spot. Where his body would disappear, and he would be a missing person forever. Without a body, no one will probably notice he's not there anymore.

Good. He has it all figured out.

...except when he gets to his chosen crime scene, somebody's already there.

A kid.

So I want to see an angry, hopeless Matt with an angry, hopeless teenager he suddenly has to take care of. Talk the value of life into him, which, you know... Matt's probably not the best choice of person for that at the moment. But he's also the only one, so. Get to work, Matty.

I want them at each other's throats.

Sniping at each other and making each other's lives hard at every step. The kid not wanting to talk and not wanting to tell who he is or where he's from, what the hell happened. Matt trying to protect the kid from Matt. Both of them keeping toxic secrets from each other. Both of them trapped together in Matt's appartement for all forciable future.

They're both angry and petty, but Matt has to be the adult in the (literal) room--- which, coincidentally, he was never good at.
