Alucard hasn't been out much since they arrived. His powers are in flux, trying to reconfigure themselves within his body. There are times he can barely keep formed, and it's not looking any better just yet. So he spends his time alone in the dark, trying to work himself back up to presentable. The only people here that have seen his truly monstrous appearances are Rip and Integra, and to a point he wants to keep it that way.

He hears the knock and ignores it at first, despite the very butler quality of it--he knows who it is, logically, but it reminds him of Walter enough that he sinks lower on the sofa he's occupying, hoping he'll be left alone to brood. But he's not going to be, judging by Alfred's voice on the other side of the door, and he reluctantly pulls himself to his feet to trudge to the door.

He only opens it a sliver, long thin fingers visible clutching at the edge of it. "Thank you," he murmurs, as the edges of him disperse, the dark cloud that makes up his body snaking out the door slightly--"but I'm not exactly presentable right now. I'll be okay eventually, it's just--difficult right now."
