Waver was currently draped over his sofa with his Gameboy. He’d angled it enough that the lamplight behind him could illuminate the screen enough to squint at while he played late into the evening instead of going to sleep at a respectable hour like a responsible adult should. The knock at his door gets him to look up, though, lowering the device and setting it on the coffee table.

He hadn’t been expecting company that evening, and only a handful of people know the workshop is there to walk past the bounded field to approach the door... Less than a handful, actually, since one of them can’t even do that despite knowing the workshop is there. One of the others only ever teleported directly into the room, negating actually passing through the field… So with the knocking, Waver felt confident in guessing it might be Ren.

The professor pushed himself off the sofa with a performative huff and moved to the door, opening it to peer out at the teen waiting patiently. A brow raised lightly, if only because there’s something almost comical about the sight. A masked individual knocking politely instead of letting themselves in. Comedic or not, he is grateful for the manners shown. People barging in on him had never been something he was fond of (even if he never kicked the people who did out). He opened the door wider and stood aside for Ren as an invitation to enter after casting a small glance around to make sure nothing had wandered past the field. It seemed to still be doing its job, though, which was good.
