Okay, I did check.
Sauce actually said quite a lot, but I've concluded that he could have used any tactic, bluff tactic or double-bluff tactic, so who he claimed to think innocent or guilty doesn't help us (or me at least).
Kath said nothing yesterday that would give me a clue why was she killed. Maybe that's in her earlier posts and I should check them too. This is the first wolf kill we can really analyse and I don't think we should waste the chance... but we should keep in mind that "to confuse" and "to avoid leaving tracks" are wolves' killing motives too...
