Private Practice's Kate Walsh heads back to Grey's Anatomy in early January for a storyline that will involve Addison, Mark and his recently-discovered daughter.
In the Grey's half of the crossover, Mark flies Addison out to Seattle Grace to perform a surgery on his daughter. The storyline continues into Private when "complications arise and Mark ends up taking [her] back down to Los Angeles to get more surgery."
Grey's Anatomy airs Thursdays @ 9pm and Private Practice airs Thursdays @ 10pm.
