[It's rare enough that Michael comes to a solid agreement with others. Alucard gains a point towards a good reputation in his mind for putting practicality above all else.]

A bell tower in which to hang upside down as a bat, of course. An important part of any vampire home.

[Now he's intentionally playing into stereotypes. It doesn't sound like Alucard is including himself in the same group as vampires who consider castle-like features an important part of the construction, so he doesn't expect him to be offended by the joking comment. He's yet to meet a vampire who could actually turn into a bat anyway.]

I would assume most Summoned are here for either business or pleasure, not seeking a new place to live. Would you leave the Free Cities for Ikorr if you could?

[Alucard's home in the Horizon seemed pretty modest. If he has a castle-sized residence back in the cities, Michael wouldn't know.]
