I would've preferred Art being in love with her and that being his reason for helping her, but her actually loving Paul even tho he was wrong for her.
Anyway, it was a good episode. I'm not sure it was strictly necessary, but it was good to spend some time with Beth considering how important she is to the story, and to the other clones. It was nice to have the season one neolutionists back too. The whole thing's really goofy, but it's so much more original and interesting than the conspiracy theory stuff that came after.
I don't remember that guys tail being so big.
