[ Right now, Oscar's expression is best described as aghast. He's not really here to roast Dipper's ability to lie but... Ozpinathan? It would actually be more believable to insist that he just happens to know another Ozpin. Oscar continues to stare at Dipper as he rolls over and only belatedly manages to swing his gaze around to Joshua. ]

No, sorry, I'm just... still getting used to this place, I think.

[ That's not a very good lie, either, but it'll have to do. Oscar steps back so that Joshua can get to work. But he doesn't think just stepping aside will be enough. He does not want to be in this room right now. But he also doesn't want to just bail when Joshua has been so helpful, so... ]

I think I should probably let him rest, but is there anything I can do to help around the clinic?

[ He tries for a smile and only manages a flicker of one. Despite that, his tone is steady. ]

I get pretty antsy without anything to do.
