The surprise makeover series “While You Were Out” (7 p.m., TLC) returns for a second season with a new host, Evan Farmer. For the uninitiated, the show follows a homeowner who has sent his or her partner, spouse or roommate out of town for a weekend, so the “While You Were Out” team can create a new fantasy space in just two days. In tonight’s episode, Baltimore wife Randy hopes that the team will help transform the bedroom she shares with her husband, Will, a man whose tastes diverge wildly from her own.

• The cable drama “Monk” (9 p.m., USA) wraps up its second season as the quirky detective (Tony Shalhoub) tries to stop a serial killer, and his sidekick Sharona (Bitty Schram) embarks on a new romance.
