Neve Campbell will soon be checking in to Grey's Anatomy, but not as a member of the Seattle Grace staff.

The former Party of Five star will appear in at least two episodes, TV Line confirms, coming on board the ABC drama as one of Derek's four sisters.

Campbell, who shared the screen with Patrick Dempsey in Scream 3, will show up later this fall and, we presume, attempt to help her brother through his difficult hand injury. Along those lines, it's a safe guess to think she'll be portraying Kathleen the psychiatrist.

Grey's Anatomy is off this week and returns on October 18 with "Love the One You're With."
