This story is my response to reading that there would be no Babs in season 4. Apple family reunion confirmed she made some new friends and moved to a new school, and was doing better, but Applejack kept interrupting before we could get any real details. I made Babs the Orange's daughter simply for plot convenience since they both live in Manehatten and are related to Applejack/Apple Bloom, so it's not too big a stretch that they might be related.
Applejack is going on a family visit to her aunt and uncle Orange, and the CMC insist on coming along to hang out with Babs again and see what her new friends are like. Along the way they run into Babs' biggest bully at her old school. With five friends by her side can they convince her to have the courage to fight for herself and her beliefs? They intend to beat her at her own game: Soccer. But can a group of blank flanks who've hardly played the sport before really triumph? Babs and Apple Bloom each learn important lessons over the day.
