As Meredith puts Zola to bed and falls asleep, she begins to
wonder -- what if her mother had never had Alzheimer's and
she'd had loving, supportive parents? The reverberations of a
happy Meredith Grey change the world of Seattle Grace as we
know it. What if she had never met Derek in that bar and he had
never separated from Addison? What if Callie and Owen had
become a couple long before she met Arizona? And what if Bailey
never evolved from the meek intern she once was? "Grey's
Anatomy" airs THURSDAY, FEBRUARY 2 (9:00-10:02 p.m., ET) on the
ABC Television Network.
