Bot might still need help from Willow from time to time, but she's not the same robot she started out to be. Just as Giles gets hit in the head a lot, Bottie keeps getting hit by doses of magic, which will cause some *very* odd things to happen within her.

While I don't establish that Robin finally got cleaned up, I think the fact that others are willing to be around him days later should speak for itself! Maybe Faith gave him a sponge bath; somebody else will have to write that scene!
