Oh, that's nice of you. [Ren claps his hands together to one side of his face in a rather childish mannerism.] I won't be able to play my favourite game here, but I'll definitely have to find a deck of playing cards sometime, I promised to teach one or two other people how to play poker...and that's definitely the kind of game where you don't want the same opponent all the time.

[If you learn to read someone's tells, then it's going to be boring playing against them. Ren's unnaturally good intuition and skill with reading deck contents and probabilities doesn't just hold to the main card game he plays.]
