Rachel sent Sunshine to the crackhouse two seasons ago and she apologized to her personally in the season two finale! She went against Kurt in season three, but backed off in order to save their friendship. She even got herself suspended for him. She supported Mercedes in the Night of Neglect and was willing to share the Maria role in WSS. Yes, she became a diva for a bit in S4 but she was willing to give up her dreams if it meant not becoming a diva by the end. She loves her friends.
