Immediately after the plane crash aftermath, Seattle feels like a graveyard for Meredith and Derek.
Every hallway reminds her of Mark's laugh, Lexie's smile, or the way her world almost fell apart.
Derek's hand is healing slowly-but the fear of never operating again is eating him alive.
When Derek's mother visits and sees how fragile they both are, she gently tells them:
"Come home. Let us carry you for a while."
So MerDer packs up baby Zola and leave Seattle for the Shepherd family home in coastal Maine-where Derek grew up, where there are no ghosts, and where his sisters can take turns helping with Zola.
