So, as the only Grey's anatomy fan here,   I will chat to myself,  I was surprised that McKiwi wasn't in it for more than 3 minutes of the new season ( well mid season)  and only had one line,  "Me too"  < that was the line, not me chatting to myself...
I thought that Kreb trying not to cry was a little overdone, and no mention of Cristina,  and yet, we know she would have flown to be by her bedside.

Hopefully next week we get back on track to see what the relationship is.  I am thinking that he was married or living with Owen's sister and she died, and McKiwi is either responsible or  being blamed.

as for Amelia,  she would be fired,  you cannot have a head of Neurosurgery who has  fallen off the wagon  and has just got sober again,
