"Grey's Anatomy": "It's so over"

First of all, let me apologize to any of you "Grey's" fans who may have missed the end of last night's season finale. "TV Guide" said it ended at 10:07, but it didn't end until 10:15...

Warning: The remainder of this post contains details about last night's "Grey's Anatomy."

So, the woman Derek flirted with is Meredith's half-sister, and now she's an intern at the hospital. Of course she is...

Derek got offered the chief job, but he turned it down and convinced the chief to stay...

Callie became chief resident and she and George started trying to have a baby. But George failed his intern exams, and he appeared to choose quitting over starting over. You can't blame him, seeing how I would guess that Callie would be in charge of him if he did start over. And of course, Izzie threw a wrench into the whole thing by telling George she was in love with him...

Alex lost Rebecca/Ava to her husband...

But the biggest event of the night was Burke deciding he wouldn't force Christina to marry him. And then he left. Does this mean that Isaiah Washington is off the show, as many had been guessing for months? I have no idea...

When Meredith told the guests there would be no wedding she said, "You can go home now. It's over, it's so over" clearly referring to her and McDreamy more than the wedding itself...

So, any thoughts?...
