Louis lets people beat him at these kinds of games occasionally, if he didn’t, no one would ever play him! This is the face he makes:
However, there have been a few times he’s been legitimately beaten, and he always takes it like a good sport, and tries to reconstruct how they managed it. Usually it’s because Lestat, who has no poker face, saw Louis’ hand and unconsciously gave it away to the opponent.
I love how in all the books, regardless of whose talking Louis is described as ‘the pretty one’. Vampires in Anne Rice novels are all described as being beautiful in some way, death making them so. But in a supernatural world populated by Beauties, characters need to spend pages gushing about Louis looks. His utter bafflement at this and the other characters gushing make me laugh every time its brought up.
