Rabastan had arrived almost immediately after Bellatrix had, deciding to hang back a little bit for the moment. He glanced up as Alecto came down the stairs, lifting his eyebrows slightly at how excited she seemed to be. Well, at least tonight would be entertaining in more ways than one. Insanity didn't really bother him, in fact it made things more interesting.
He decided to leave the explanations up to Bellatrix for the time being. He would take care of Alecto the rest of the time, as promised.
