The series wraps up its third season with "Looking for Mr. Goodbrain, Part 2," which finds Liv (Rose McIver) continuing on her not-too-selective path of seeking romantic partners — the byproduct of her assuming the personality of someone Ravi (Rahul Kohli) had ties to. However things turn out here, rest assured there is more brainpower to come: The show has been renewed for Season 4. Malcolm Goodwin, David Anders, Robert Buckley and Aly Michalka also star.
