[Ren's mouth twitches up a little more as if he's stifling a laugh, and he curls a hand against it to disguise it some. Granted, the icing still on Molly's upper lip is contributing a lot to how hard he's having to try to disguise that amusement.]

And that seems to suit you fine, but not everyone wears it so openly, you know? I only like to show my hand when it benefits me to do it. [As fitting any good player of games of skill and chance. He tilts his free hand to exaggerate the point.] It's true, it's a little fun to play with people who know me enough to expect it...but it'd be such a waste to extend that privilege to just anyone, right? I want to make sure they're interesting first...

[It's getting kind of hard to not get distracted by that stray icing at this point, though, and he points towards Molly's upper lip, finger only inches away.] Do you want me to get that for you, by the way?
