When I saw her break down after meeting Twilight again, talking about how her best(?) friend not going to her party made her fall into abyss, lose self-worth, become a workaholic to keep the feelings bottled, it made me feel something. I'm glad this was resolved, but I felt it should've been expanded to two episodes or so, to underline how easy it is to accidentally hurt some ponies deeply.
Interesting horsie.
