His drink arrives and he takes long, slow gulps off of it, mostly to hide his dry expression. Yes, perhaps the Principate is drunk enough already if he didn't catch that that was a blatant invitation to his place.]

Yes, William, I am inviting you back to my room.

[A touch on the snarky side but he means it, and clears his throat.]

More that if you ever don't feel like going down five flights of stairs you only need knock on the next door over. But I would not be opposed if you wish to head up stairs.
