Amelia (Caterina Scorsone) faces the fight of her life on Grey's Anatomy when she goes under the knife to have a tumor removed from her brain. Fortunately for the neurosurgeon, she won't be alone.

In this exclusive clip from Thursday's episode, she decides to shave her head while Meredith and Maggie offer up some much-needed moral support. "Kinda makes you look fierce," Maggie says of Amelia's new style.

The episode, titled "Ain't That a Kick in the Head," will also see Meredith (Ellen Pompeo) dealing with the fallout from her revealing conversation with Nathan (Martin Henderson), and Jackson (Jesse Williams) receiving some big news.
