This has the potential to be a really good story. I can see Applejack and the others helping Flim out once they realize that he truly is worried about his brother Flam and have no idea where he is. After all, Flim and Flam may not be the greatest of ponies considering what they have done in the past but I can't see them turning someone down who is truly in need of help. Plus this could be for a good potential mystery as they try to figure out what had happen to Flam and some potential character growth and bonding mixed in.
