It is about time that the writers addressed her emotional state and the need for it to finally come to a head. I mean how long can one woman hold all her emotional problems inside before they finally boil over? and Cal has a lot of emotional baggage. Not to mention her need to be perfect and not make a mistake.
I just hope the team rallies around her the way she has always rallied to their side when they are in need of help. She has always been the 'rock' of the team, so it will be interesting to see how the team deals with her making a mistake and not being the one to lean on.
I think Emily will rock this episode and it is sooo cool that she did her own stunts. She totally strikes me as the person who would want to get down and dirty and do them herself.
