Oh yeah, yup, she's seen this before.

You've been glued to your work for hours. Fixated. You've barely moved. At least you've been drinking coffee - she's made sure to deliver it - but the sandwich she brought went barely touched. You're clearly having a hyperfocus spell. She's pretty familiar with those. Had 'em herself. Seen 'em plenty in others. Studied 'em, too.

People forget, sometimes, that Harley was a psychologist. She gets this stuff. So she knows what she's looking at! And look, it can be great for getting some work done, no denying that. But also, pretty bad for anything else? Like, y'know, eating, and sleeping, and general function?

But she also knows what hyperfocus interruption does, and... yeah, people tend to get, ah, irritable. Because you're focused, and you probably feel really productive right now, and sure, your work is important! But so're you. Like, your health and stuff. So that's that - she's just gonna have to pull you out of this. Because you've been here since before she even got up, and you've barely eaten, and that's probably been too many cups of coffee really, and it's way past bedtime.

Harley sidles up next to you, exaggeratedly casual. "What'cha workin' on?" She'll start with an indirect approach, maybe that'll go over a little better. Ease in. Gentle touch.

Though if she has to go the direct route and drag you away from the desk, she's not above that. She'll do it, see if she won't.
