Combeferre is feeling the sort of scientific curiosity that verges on either recklessness or pointlessness. "Good evening, Bahorel. Truth or Dare?"

The purpose of this game is to entertain oneself by watching one's friends squirm with shame or fear or both. Bahorel knows little of fear and less of shame. But Combeferre has always liked a challenge.

(He considered Joly, but he feels more protectiveness towards Joly, and he also knows it's possible to make Joly feel embarrassment. He's not at all sure of this for Bahorel.)
