If you've seen the promos for this week's episode of Grey's Anatomy, you know Meredith Grey has an impossibly difficult problem on her hands. Her father, Thatcher, who saddled her with abandonment issues and made her dark and twisty for decades, needs a transplant.

It looks like Lexie is not a match, but Mer is. She could be his last hope.

Should Meredith help Thatcher, her estranged father, who returns to Seattle Grace? Should she do as Lexie pleads, and give her her dad? Or, as Derek says, does she really not owe Thatcher anything after all the misery he's caused her?
