Okay. Yeah. So Jason's the last guy with any ground to stand on when it comes to lecturing someone about sneaking out at night. Sure.

And look, what you're up to? Not really any of his business. He gets that. Heck, he wouldn't've even noticed if he hadn't been out himself at odd hours, yeah? He just happened to swing by and spot you climbing back in your window the other night, not in costume, not going in through the Batcave, so clearly, y'know, not 'just coming back from patrol', which he's pretty sure is the go-to excuse here.

Should he probably just leave it alone? Yes, yes he should. Is he going to? Pfft, absolutely not. Look, being the family troublemaker comes with responsibilities. Privileges. Expectations. Namely, he gets to do what he wants and hear the lecture about it later, but he's also kiiiiinda the guy who's best-positioned to spot - and, if he deigns to, intervene - when one of the rest of you is possibly getting up to something too ridiculous.

...Also, he's got it from experience that the sort of things that might lead to somebody in this family sneaking out in the middle of the night aren't usually good news? Look any of the 'good stuff' someone could maybe be sneaking out for, you all already get up to fully sanctioned, he figures. If whatever you're doing isn't something that can be handled on patrol, you're likely either in trouble, or up to it.

It's not like he's worried about you, he just wants to make sure you're not being an idiot.

So, y'know, stakeout time. He's supposed to have left town that evening, but here he is, having doubled back around after putting on (he thinks) a perfectly good act of leaving a few hours ago. And now he's parked himself in a spot on the grounds where he can keep an eye on your window, vaguely wondering if maybe he'd just caught a one-off.

Luckily for him, he doesn't have too long to contemplate what his plan B is if you don't get up to anything tonight, when he spots the window sliding open.
