I thought it was a fun episode, if ultimately a weak episode.
The Henry/Grace stuff was very awkwardly handled. For starters, Grace bought Henry's tale a little too easily. There really needed to be one throwaway line where she said, "That's why you've been so weird these last few weeks." Then at the end, I didn't buy her making him the care package at all. Okay, sure, Henry's "elation" memory was seeing her, but even so that's a pretty hefty emotional blow to find your husband is not your husband.
Where did we see TINY before? I can't for the life of me recall.
The Grant/Carter bickering got old really fast. It (and the very similar Stark/Carter bickering) works when it's only a scene or two, but the whole A-plot? For me, it got tiring to watch and took away some of the punch it should have had. However, respect to the writers for actually calling out that Carter hasn't made a move on Allison. It's tough to be sympathetic for him when he's not even trying. Also, why the hell isn't Allison involved in this? Doesn't she get a point of view?
I don't for a second buy Fargo as as good a driver as he was.
EMO (heh) reminded me of Robby the Nintendo robot, mixed with a bit of Wall-E.
