ABC has released some promotional photos of the October 1 episode of Grey's Anatomy, entitled "I Always Feel Like Somebody's Watchin' Me," in which Izzie totally wigs out.

Literally. Check out the reddish-brown hairpiece on Katherine Heigl's character ...

Cancer-surviving Izzie, famous for her blonde hair, dons a new wig.

The official description of the episode: "Several weeks after her near-death experience, a recovering Izzie returns to work." She looks to be in good spirits, at least here.

The synopsis continues: "Nervous that there will be layoffs in the wake of an announcement from the Chief, Seattle Grace's residents compete to survive impending cuts."

That includes Cristina (Sandra Oh), who "attempts to work alongside Arizona (Jessica Capshaw) in pediatrics. And Bailey (Chandra Wilson) and Alex's (Justin Chambers) patient's already complex case is further complicated by her schizophrenic son."
