"Hey, I can help! I know first aid!" She waves a classic red bag with the plus symbol.
And then they're shoving her at him. Punk-ass teens in a moderate level of panic.
"Now, listen up- I can help him, but I need to cut open his throat and insert a breathing tube." Pause, eyeroll. "Shut up! Stop arguing while your choom's suffocating! This is standard ripperdoc shit! Fuck. Hold him down!"
It takes another minute of tense, heart-pounding adrenaline to get it done. The breathing tube. The throat hole. Her hands guided by her power. Blood on the concrete floor. Rapid emergency tracheostomy... Not ideal, but better than 'dead'.
The guy stops making those awful choking sounds. She lets out a deep breath and sits back. "He's gonna be fine. He'll be fine! The ambulance is coming, yeah? Look, they'll get him to the hospital, or a ripperdoc, and this way he'll still be alive when he gets there." ... "No, there's nothing else I can really do now. Don't let him hit his head. Talk to him, tell him to calm down. I can't fucking understand Japanese. Yeah, I'm a hafu, shut up. Goddammit."
She's still there five minutes later when EMTs cart the kid off on a stretcher, his buddies cornering her near the elevator and making it clear she's not allowed to leave.
This was a mistake. Her power is whispering ideas to escape with her little medkit, to her- Choke them with the long bandage, throw the disinfectant in their eye, stab at a tendon with the swiss army knife- But that would just make things worse. This is a fuckin' gang.
