After saying goodbye to two of its own earlier this season, Law & Order: SVU is welcoming back a familiar face. B.D. Wong, who starred on the NBC drama for nine seasons, will reprise his role as Dr. George Huang in the season's penultimate episode, TVGuide.com has learned exclusively. In the episode, titled "Thought Criminal," Huang is brought in as a psychiatric consult to evaluate and testify about a suspect who's on trial for attempted kidnapping and the rape of a child. Wong's occasional visits to SVU have helped maintain ties to the show's former cast, which has undergone some transition as of late.
