On January, Private Practice's Addison (Kate Walsh) will head back to previously where she belonged: Grey's Anatomy!
According to Ausiello, Mark will call Addison back to Seattle Grace to perform a surgery on guest-star, Leven Rambin (Terminator: Sarrah Connor Chronicles). But in the end, Mark will have to bring his patient to Los Angeles for more needed surgery.
Will this rekindle something between the two?!?
