So yeah, anyone who hasn't heard of the book, it's seasons one and two in the POV of Joe and Nurse Debbie. I'm reading Joe's half now and I found a little something that made the shipper in me squeal.
"I must admit, part of me is glad I survived the surgery just to see what ends up happening between Meredith and Derek. And, of course, George and Alex. No, the latter couple isn't an item...yet."
--Joe, pg. 34. Set after the S2 premiere.
JOE SO KNOWS! Can this thing be taken as canon? Haha.
