There is a whole jangle of things that could hit wrong. The psychic hiccup where he senses Daniel pausing over his incorrect French, Louis' absence of clear confirmation about whether he deserves his number because even though Louis did very much try to give him that thing already, there is no underestimating Lestat's ability to feel ignored or excluded, and speaking of, Louis has been to New York, has visited art, undoubtedly with Armand, and he wouldn't have thought to ask if Louis would like to see exhibits because he doesn't know save from a book what Louis has been up to—

Anyway. White noise. White noise dissolving into a whine at the back of his brain which quiets down because Louis wishes to come to New York to see him (and Daniel) and doesn't wish to impose on him (and Daniel).

The breakneck change from the beginnings of a tantrum to a fond smile is probably only assuring in a short term kind of way. He's still charming.

"I would like that," sweetly, earnest.
