This is open and vague, but has a subtle absurdity that propels it when it probably ought to have dissolved into random shouting. Ever heard Eddie Izzard’s description of English movies? People opening doors in houses, etc. “What is it, Sebastian? I’m arranging matches.”

Funny and tantalizing, with just that one little hint they’ve done something really bizarre with the mention of the ectoplasmic voicebox. I’m not generally a fan of present tense, but you made it work here.
