I hate to make another comparissons, but since the subjects of this episode friendship, I have to say the MLP writers do a much better job than the LPS writers. LPS are good with comedy I give them that and entertainment, they need to learn how to wrap episodes and deliever a good lession or moral.
Clearly the Biskit twins have some social skill problems. They overacted to Blythe helping them, a simple thank you would have been enough. I feel sorry for them actully, they despretely want friends, but they just have terrible social skills, and think the only way to get friends is to buy them, thanks a lot Mr. Biskit, you really messed up your daughters. And Brythe doesn't realise that, that self centered girl, can't you realise a cry for help when it is right in frount. Maybe I am spoiled on MLP because I know Twilight would have handled things better.
And that bully in the episode, she obviously has issues with her height, I thought Brythe would have befriended her at the end, way to go Brythe, Twilight would have resolved that.
And Brythe's friends I didn't like their attitude when Brythe was befriending the Biskits, ever heard of being supportive even if you thought she is making a mistake. In a similar situtation, it was handeled much better in "Griffen, the Brush-off", Pinkie Pie and the others never gave Rainbow Dash an ultimatum like Brythe's friends do here. The Mane 6 > Blythe's friends whatever there names are. Like I said before, I think I am spoiled on MLP and their great writing especially on the subject of friendship.
As of the Pepper plot, Penny was being a bit sensative, but she took it too far. No one knows about sensitivity on this show.
