[X] Tell them it was an assassin, but nothing besides that.

...IllonaxDiceRollerOTP. It continues being true...
Anyway, on the choice. Yeah, the result of critting during the combat was something that let us get physical information on the assassin, which happens to coincide with the physical characteristics of lovely Mister Brice. I'm going to jump right on this paranoia train -- he is not included in the loop. He doesn't even see the loop. In fact, if done properly he should be totally unaware that a loop exists.
But fortunately, they as of yet shouldn't expect Illona to make such a ludicrously paranoid leap to conclusions even if it does turn out that somebody cracked a mask. So, given that we have deduced their likely treason through the power of insane luck and ludicrous paranoia, their planned ambush is A) dead; and B) a now-ambushed ambush, which is a supremely unhappy ambush indeed. For them. We'll have fun. And celebrate, in the name of ludicrous paranoia.
So! A wedding. I love weddings; drinks all around! No, I don't feel that the wine is more bitter than usual, Lord Straydor. Why, have the servants given you dregs? Dear me, is that a cough you have?
I should probably stop gloating. I make rolls in my own quest, and I don't need the bad juju...
