"What do I want?" Michael flashes a somewhat maniacal smile - selling it as fully as he can without firing a shot. "I want you to apologize for shooting my associate, and I want you to get the hell off this train."

He digs the gun against the girl again, eliciting a loud cry that tugs at his soul in a way he knows he'll pay for down the road despite his good intentions.

"It's your choice, Pierre. You can walk away from this now or I can take care of the reason you're here."

If he doesn't walk away, Michael knows he'll have to think fast and aim even faster to take him out - and he's ready for it. His goons are distracted enough that as long as he acts fast he should be able to neutralize the threat without any civilians getting hurt. He kind of hates running on should though.
