After the years went by they started to loss a lot of money so rainbow bazer had no choice but to join the knights for some extra cash for his family. Unfortunately the crystal empire war broke out an he never return home. So rainbow dash was stuck with her mother was forced to work over time an never even spent one second with raibbow dash even when she had time for a brake. a mother who never showed affection towards rainbowdash  she then started to turn to super hero books an getting advice from all the comic books an adventure books she read.
