"That's not what I meant." Now he snapped back because Remus really couldn't believe they were just going to continue this argument now.
For fuck's sake, he should have just let Regulus go to jail -- not that he could have done it. At least, if Regulus was locked up, they could manage to go twelve hours without fighting.
"Regulus, stop." Remus did move then, catching his lover's arm in a loose grip. "You've been out all night. Passing out does not equal decent sleep. And you're only just sobering up. Whatever you're about to do, it can wait. Harry's going to finish his shift before he does anything. You can do whatever you're contemplating after you get a couple hours' sleep."
Hell, one of them ought to get some sleep and it clearly wasn't going to be Remus, especially not if Regulus was about to do something stupid he didn't want Remus implicated in.
