I KNOW! I just finished watching it and it made me SO HAPPY. Bailey loving sci-fi/Star Wars was just the greatest. Callie kissing Erica OMGYAY! I am so glad she's taking the chance. I always had faith Shonda would go through it :) And HELL YEAH to Cristina as well as being over the moon with her teaching Lexie as well. I love when she grows as a person. And they really are the OTP. The overall happy feeling was definitely very, very nice.
