I liked that Spike didn't act like a "dummy" in this episode, if you get what I mean.
Poor Spike is routinely handed the Idiot Ball in his episodes. There seem to be 2 Spikes: one is a voice of reason when Twilight is stressed or acting unreasonably, the other is an arch-klutz who exists solely to generate Complications. Only the latter tends to see the light of day in Spike episodes, so I generally approach them with trepidation.
I have not yet seen it, but I am now looking forward to the episode, if it indeed features Spike-1.
