Well, I haven't seen this episode in a while, so if I forget something, that's why.
Okay, I thought this episode was really good. I especially like the Rain/Margaret action. Not until this episode had I thought of Rain and Margaret as a couple, but I can see it now. They both are the "sidekicks" of Sadie, and me being a Harry Potter fanatic and Ron/Hermione shipper, know that sidekicks are meant to be together. =]
Anyways, I think that they should've continued that lead farther then they did. But, I guess that it's their show and they can do what they want to.
As for Hal and Arden's date, I don't remember it that much, except for the fact that Arden thought Hal was stupid. I won't go on with that part, seeing as I don't remember it.
I think that this helped the relationship between Sadie and Hal grow a little. Maybe not drastically, but they do act like the at least like each other!
Okay, so see the episode if you can. Especially the part where Rain/Margaret actually kiss. It's cute. X)
