15 Essential "Grey's Anatomy" Episodes For Meredith-and-Derek Fans

By season nine, most of us found comfort in Derek and Meredith's rock-solid relationship as drama sparked between all the other couples on the show, like Cristina and Owen. Meredith and Derek find themselves attached to baby Zola in season seven and eventually adopt her. Without really expecting a baby, Meredith finds herself pregnant in season nine, despite her doctor telling her that her uterus is "hostile." She buys an adorable "World's Best Big Sister" shirt for Zola and mischievously asks Derek to look at it.

This moment reminds us that good things can still happen in the "Grey's" universe, even after terrible things like the horrendous plane crash in the season eight finale.
