When somepony loses everything they thought they knew, it is very hard to start over. For Trixie, it will be a long, arduous road. For Glimmering Shadow, he has not even started down the path of recovery yet.
I am a BIG Rarity fan. I am also one of the biggest Gamers you will ever meet. My favorite MLP FIM episode is a tie between A Friend In Deed and A Dog and Pony Show.
