I originally thought the idea of having a Big Bad that used psychological torment was brilliant, because your own doubts and fears are the hardest to fight. "The only thing we have to fear is fear itself," in other words. Unfortunately, I don't think the idea was executed well in a lot of ways. It would be an obvious thing for TFE to set the good guys against each other, pouring poison in their ears to divide and conquer. It did that in the earlier scene with Dawn and First-Joyce, saying Buffy won't be there for you; Chloe being driven to suicide, and then appearing to the Potentials is maybe another instance. But the concept didn't get built up enough, so Buffy being kicked out just seems abrupt and out of character for a lot of the people, as others have said. TFE did sow doubt, but not much toward this end. Once again, it's the result of trying to cram too much into a season.
I did enjoy seeing Clem on his way out. Though SMG seemed to have a cold in that scene. Just one more thing piling on Buffy!
Xander is usually the wisecracker, of course, so his sad face and attempts at jokes in the hospital, was just heartbreaking to me.
"I guess I'm just ornery." Loved that line. Correct me if I'm wrong, but Buffy never saw any ghost that she cared about, only Potentials that she didn't always realize were dead, and Caleb. Buffy can't be psyched out like the others, and TFE seems to know this. This is a strength, but it might also mean that she is less able to understand the feelings of those who have been presented with a loved one, because she didn't experience it herself, and she's just tougher.
Yay, road trip! But I'm with Andrew that you need snacks. And the return of onion blossoms, which they never really did explain why Spike eats. Or why he considers knowing the recipe for them to be so embarrassing that he threatens to bite Andrew if he tells anyone. Anyway, it's a welcome light scene in a heavy episode.
