[He furrows his brow and puts his glasses back on as Cisco closes the door, crossing his arms and waiting for something to happen. His ears can't make out whatever Cisco said, but when he pulls out the envelope he seems to get the message. His hand goes for his chin, rubbing it carefully as Cisco explains.]

So you pulled that envelope out of there, but it wasn't there before? Fascinating...it could be related to quantum physics. The concept that something can be moved from one space to another, maybe even being pulled out of that previous space. It existed somewhere and now it doesn't exist there anymore, it's here, and the closet acts a gateway.

[He hums and drums his fingers on an armchair. If it's not that, it might be something meta-related. At worst, it's magically inclined and he can't work with that. Mainly because he'd first have to explain to Cisco that magic is actually real, no science attached to it.]

That envelope - we should open it and see what's inside, or if whatever is in there is still intact. Want to do the honors?
