Jason knows his hands aren't built to take care of someone. He has his motivation, and it's destructive— he'll level all of Gotham if it means he can achieve his goal and kill Bаtman.
Yet, he still finds himself getting distracted. He should be working on his next move, commanding his militia, and instead, he's giving his attention to a child. Bаtman has been destroying the drones the Arkham Knight has placed all over the city, and what is Jason doing?
"I told you that you can't go out there." Jason grunts, lifting the most recent source of his problems up to sit on the counter. "It's dangerous. Too dangerous. There's looters, and rioters... and Bаtman."
Jason knew that Bаtman works quickly before he started all of this. He'd anticipated it. Planned for it. Now he has to factor in protecting this kid he'd taken in, left behind after the mandatory evacuation of the city. Really, it was one of his men that found the damn ankle biter— reportedly, there was no parents to speak of. Jason hasn't pried too hard into what's almost certainly a difficult past for the child.
"You have to stay in the safehouse." He reaffirms, leaving no room for argument in his tone. He can't believe he's really here, lecturing a child like some kind of father. Jason does not have good experiences with fathers. "You shouldn't even be awake right now. It's one in the damn morning."
He shouldn't have let someone get so attached to him. The kid is like a barnacle that he can't scrape off. He's worried, of course, about what would happen if Bаtman discovered their existence— the old bat wouldn't hurt someone so young, but it's hard to imagine he'd just sit idly by and allow a criminal like the Arkham Knight to take care of a child.
