8 parts Complete I think that Meredith and Derek, with their flaws and successes, helped each other develop throughout the first seasons. Meredith was scared of commitment and had suicidal tendencies, but then became a good surgeon, wife and mother. Derek was at loss and could only see black and white, but then he found new life ("It was like coming up for fresh air") and was changed for the better as far as his relationship with the patients. Right before the show kills Derek off, they lose all this, especially in season 11. This is why I'm writing this fan fiction.
Plot:
The plane crash survivors haven't managed to buy the hospital (GA 9x17), so it's time for everyone to find new job and life opportunities. Meredith and Derek decide that their Seattle chapter is over, and they're ready to start their Boston chapter.
I've kept some scenes I actually loved from the season 9, 10 and 11.
Warning: English is not my mother tongue, so there may be mistakes.
