Don was never interested in MLP or anything, while his friend Samantha (or Sam for short) is a total pegasister. One day he caught her up, as she was watching "Call of the Cutie", he couldn't help but ask what all the fuss was about.
He was never a fan of someone's destiny being predicted beforehand and in result the whole cutie mark thing went totally against him.
Sam isn't completely against the idea, just wants to have a choice.
Now, let's throw two blank flanks into Equestria.
