AAAHHHH so good to have it back!
My thoughts-
HATED the new credits. Tom had previously told me they were going to do that as he read it somewhere but I still HATED it. The credit sequence gets me so excited and I love the theme tune! Why change it? I was most upset.
Ok- onto the actual episode.
Luby scenes made me cry...they are both just *such* good actors the scenes are really moving. Especially the one where she said she didn't want Joe to be alone! I really felt for her being so helpless

Didn't like Luka flipping out in the toilets though.. a bit cliche IMO, I know he's had trauma and all but why does everyone have to throw things at mirrors?
The whole hysterectomy thing reminded me a bit too much of Carol giving birth to the twins...but I still felt really sorry for Abby

The video phone thingy was so sweet though. And I'm SO glad they called him Joe...for some reason I thought I read somewhere it would be Damien?? Joe is much better!
LOVED LOVED LOVED Neela saving Jerry's life. She is obviously going to be an awesome surgeon

yay! Although...why didn't Abby ask Neela how her husband's funeral was when she came into the hospital? Meh.
The Sam scanes bored me. I was disgusted by the rape thing though...and she did act well in them but I'm just bored of the Steve storylines now. Glad she killed him!! And as afor Alexbot...the less said the better. "I like Chicago" hmmmmm...
All in all, excellent stuff I thought. Definitely very good to have it back.
Best line-
Abby: M-mongo?
(followed by Luka's GORGEOUS SMILE!!!!)
OOOH I also LOVED the use of the David Gray song...thought it fitted perfectly.
No, your name's not Susan and it never will be
