Cornwallis is in the next episode, and judging from the description, they'd have to go out of their way not to address the foot-rub thing. 

Someone asked Andy Bobrow on Twitter yesterday if she would be back this season, and he replied "Sadly, no."

I'm guessing it was an attempt to forestall some fan nitpicking, and acknowledging that Duncan really ought to be conducting the group therapy, without actually explaining where he's gone.

"I also found it odd that "I've never voted" and "I accidentally caused a giant fire that destroyed a bunch of stuff" were supposed to be equally embarrassing revelations."

I'm a sucker for the soft stuff, so I'm inclined to be forgiving of this episode.  But what are we here for if not to carp?

Come to think of it, the Magnitude thing was kind of like Pierce buying Troy and Abed's special handshake towards the end of season two.

Apropos of nothing: Vulture has a short interview with Wallace Shawn, and he's asked about Community's My Dinner With Andre homage.  He doesn't have much to say about it, but he did see it and like it.

It's not quite clear what age Jeff is supposed to be, but he is at least a few years older than Britta, so the age gap between him and Annie is greater than that between Britta and Troy.  You're right, though, it is one of the reasons that their relationship (what little of it we see, anyway) feels a little odd.

"Troy fails because he can't command respect"

Absolutely.  I love the Dean in his school booster mode, and it was a relief to see that the show doesn't always have to resort to sticking him in a costume to get laughs.  I enjoyed this episode more than any other so far this season, and it was mostly down to him, from his presentation at the beginning ("Pierce has…

Is the source material any good? It's too hard to keep track of Scandinavian crime novelists - at this point they seem to outnumber Scandinavian criminals.

But we're still supposed to think Jeff was a jerk for being suspicious of Chang, even though he was right.  Just like we were supposed to think Jeff was a jerk for being suspicious of Pierce on Halloween, even though he was right.  And sort of like how we were supposed to think Jeff was Hitler-esque because the group…

There's an episode commentary somewhere where Harmon diplomatically (for him) calls Chase a "brilliant soloist" who's best when left by himself.  Maybe Chase preferred that, or maybe by that point he was too unreliable to trust with anything more.  Either way, I agree it's a shame.  As others said last week, Pierce…

It's true that Harmon left open the possibility of Chang as the villain, but I wonder if he had any intention of following through.  Didn't he always say that the third season would be the darkest, but that it would pass?  If they followed that story cycle, the show wouldn't have a place for a full-blown villain.

I'd say the pottery class - "Jeff, you're Goldbluming" - remains the gold standard.  And, of course, there's the season 2 premiere.

Chang has always been a problematic character, as Todd notes, but he has his moments.  What are your favorites?  Offhand, these would be mine:

I didn't see any good reason why this episode needed to be told in documentary format, either, but I'm afraid I might just have been missing all the references.  (I had no idea about the Grizzly Man reference until Todd pointed it out, for example.)  The story didn't seem to depend on it, and it didn't even seem fully…

All I could think of was end of the recent Halloween episode, where Pierce said (paraphrasing) "You never suspected that I was messing with you all along!"  And Jeff replies, "That is literally the first thing we all suspected."

I never thought I'd say this, but Chevy was fully justified in walking out before the season finished shooting.  I'm amazed he put up with this material for this long.  Pierce's character was mined for just about all it was worth in season 2, and Chase is legendarily hard to work with, but damn, he didn't deserve to…

Frank?
