Another sterling episode! Peter Krause rocked, too–well, they all rocked, but Peter really got to show his stuff, imho. As much as I have disliked the Lisa character, I really love Lili Taylor’s performance and actually am coming to like Lisa more, so will be upset if she has met her untimely demise.
I don’t know what to think might have happened to Lisa–I’m leaning to “she might have gone off on one of her vision quests” but can’t explain her not telling anyone anything nor leaving Maya and Nate behind. It will likely be carried over to the next season, leaving us hanging until then.
Everyone was snapping at everyone else last night–poor Arthur too, he’s really trying his hardest, imo. While he is strange, so is Ruth and honestly I was coming to like this couple; they had quite a bit in common and seemed to mesh well together. I hope that there is more to Arthur than what we’ve seen and that AB is going to explore it. I hope. (Alan Ball, are you listening? :))
Claire really let Olivier have it, and he gave back just as good! I wasn’t surprised at the result of her pregnancy test, yet am wondering if Russell is the father or could it be the guy from the crematorium that Claire was seeing for a while?! Poor Claire, she’s got a lot on her plate.
Mrs. Chenowith is, I think, sicker than Billy, but she’d never admit to it in a million years. Geesh, that woman is off the deep end–much further than I had thought Lisa was.
As to Billy… all I can say (again) is EWW! and maybe BLECH! Jeremy Sisto is excellent in the role, though. 
Rico and Vanessa seemed a bit aimless last night; I think her sister is still mad about what happened with her husband; didn’t someone else mention that possibility? The sister and Rico really do not get along. Those large credit card purchases are definitely unhealthy for dealing with depression–that sister is -not- really helping. 
David and Keith seemed headed to the big bust-up, unfortunately. I really do like those two together; both of them have issues, though–not just David! LOL
Such a great show, and what a wonderful cast; too bad we only get two more episodes for the season. I’ll enjoy them to the fullest.
