[Stiles resists the urge to bang his head on the nearest wall and oh god, why did he ever think he was cut out for being a warden? Seriously.]

Obviously not, no. I think you should put it back since it's not yours, mostly. And not to be a buzz kill, but if you don't then...

[Then what, Stiles? he wonders.]

Then I'm gonna report your ass to Gwen. She's your temporary warden, right?
