Goddamnit.
It's bad enough to be benched. Look, it was a stupid situation and he got in over his head and he knows he's lucky he walked away at all, okay? He got hurt, and now he's on mandatory house arrest for recovery. Jason's definitely not thrilled by that. But it's not the first time, and it's not gonna be the last. So whatever.
But then there's a friggin' crisis. All-hands-on-deck level crisis. Well, 99% of the time that means the Clown, and he's pretty sure this is no exception, because nobody will tell him exactly what's going on. Just that everyone's gotta rush off to deal with it. Hell, even Alfred's AWOL - well, he's down in the Batcave running interference, actually, but he's not in the Manor. And Jason? Has to stay in the Manor. So that sucks.
But what sucks worse is that he's not actually stuck home alone. Because there's somebody else who's not allowed on this mission. Which, frankly, all but confirms the Clown's the problem, doesn't it? 'Cause it's his damn kid who's also got house arrest orders now. Just Jason stuck injured and benched during a city-wide crisis, left babysitting the Joker's freakin' kid, because he's the only option available to do it.
Stuck having to sit around 'keeping an eye on' the kid he's been spending the better part of the last few months avoiding like the plague. The newest 'Family member' he still can't seem to accept as family. While their dad's out there probably trying to blow up the city. Again.
So, yeah, you could say he's having a bad day.
So maybe stomping into the sitting room and declaring irritably, "Alright, I'm in charge until everybody's done with whatever crap's going on, so no funny business," is not the best way to start things off? But he's already angry, and he's sore, and he's not thrilled to be here, and he's maybe kinda borderline panicky about whatever's going on out in the City and what's happening with the whole rest of his family. So he's gonna be as grumpy as he damn well pleases, alright?
