I loved this season of Grey's so much I had to buy it.
My favourite episodes would have to be the ones in which Merideth drowns and Bonnie, Denny, the nurse who was friends with her mother, and the bomb disposal guy are with her in her afterlife to make her try and appreciate life more.
As a person who reads into things, I can see the slow transformation of the main character Merideth from ‘dark and twisty’ (mentioned in season 2, episode 1), to slowly coming out of her shell and becoming a more happier person (although it takes ages and she is still indecisive).
This season kept me entertained and I loved every episode, definitely worth buying!
