I'm not sure why
Alcarillo's suspicions of
Sauce combined with the fact that Sauce voted for him and the next Day Sauce was dead make Alcarillo look bad. At that point we didn't have a Seer, so if Alcarillo is a Wolf, he couldn't be afraid that a Seerish Sauce would have dreamed of him. As to posting in character, that's what many of us have done here. (Oh dreadful day, my husband is dead! How shall I manage with my children all by myself!

)
But I'll go his posts through myself (no offense to those who have analysed him already).
#17 - Says that even though
Cailín might have raised
Eomer to be a lady-killer, he did not raise his son to be a murderer. He will stand by my family. Says the whole family of
morm's "reeks of werewolvery". Doesn't like the fact that
Diamond playfully predicted that Cailín will get lynched. Every defence and suspicion here is based on the relationships in the Village although if he's a Wolf 1) what would be a better way to smoothen reactins than to disguise them as family banter, or 2) he might not have been a Wolf yet
#33 - Di explains her prediction of Cailín and Alcarillo is comforted since someone approves his son (Eomer). He isn't as pleased with morm and
Celuien. Says that he and Cailín do not allow black magic in their household. Says that lynching the GW (which isn't possible since he can't die by lynching) would make our situation harder and he'd prefer hunting the EW instead.
Gurthang said that he'd like to lynch people who would not be obvious Seer choices, and he names Naria, Alcarillo, Azaelia, Lommy and Lalaith. Alcarillo's reaction was: "You want to lynch me?!

I have to be careful of what I say from now on..."
Okay, this looks odd. Gurthang had five peope on his list and considering that, Alcarillo's reaction was pretty strong.
#124 - Says that if he were the GW, he would have chosen Azaelia, Oddwen, Roa, Diamond or Gurthang as Gifteds because they tend to last long "whether by being clever or by flying under the radar". He also says: "True that that's also great when playing a wolf, but I wouldn't lynch these folks yet (especially not myself!)." Reminds everyone about
Fea's suggestion that the EW is someone who has enough time for it, so s/he's not probably a student.
Again, defence for himself only for appearing on a list with a bunch of other players.
#144 - Defends himself, family banter, suspects
Sauce because of his lists of potential Wolves and because he fits in the criteria that Fea gave. "Couldn't he be the EW?" ~Alc
Uh, the dreaded polling... At least he gave some of his thoughts, but they seem to be based more on others' opinions than his own.
#159 - Votes for Sauce because of his "crazy theory

".
Well, this look a bit interesting. Why would he call his theory crazy and give a smiley? Perhaps he did know that it was likely be wrong and his vote wouldn't tell much. Still, this was in an early stage of voting, so his vote had value in it. Perhaps it was a way to clear oneself if we for some reason had lynched Sauce and found him innocent.
#222 - says that it looks like that he has some defending to do. And that's what he does. Almost the whole post. He also asks quiestions why he would have killed Sauce, and the post ends with village banter.
#353 - says that
Zali wouldn't surely want to lynch a future family member. Agrees with
Eomer and votes for
Nogrod.
#371 - Laments
phantom's death.
#394 - Asks people to slow down and says that the last post was just roleplaying. Tries to explain his defence after Sauce's death.
#622 - Says the GW knows much more than us, finds
Roa's "rebellious behaviour" unsettling and votes for her.
Okay, I see that he really is defensive, and on that basis he looks somewhat suspicious right now.
