A familiar face in the corner makes a wisecrack and the Unforgettable cast hold back their laughs. The Saturday Night Live alum's addition to Unforgettable is part of a mid-season tweak for the CBS procedural, which stars Poppy Montgomery as Wells, a driven cop with the extraordinary ability to remember everything she experiences. Despite consistently besting time-slot competitors Body of Proof and Parenthood in overall ratings and demos, the crime show is no sure thing for renewal. Carrie and Webster "quickly bond," Montgomery reveals, especially when the doc volunteers to help Carrie investigate her sister's unsolved murder - the one case in which she can't recall the most important details. Tonight's episode amps up the adrenaline with the introduction of a serial killer determined to get under Carrie's skin.

Fan fave Joanna Johnson is returning to the role of Karen Spencer on CBS' The Bold and the Beautiful in March - and she's not coming alone! TV Guide Magazine has learned that Karen will be bringing along a daughter the audience never knew existed. The kid is named Caroline, after Karen's late sister (also played by Johnson), and she's a twentysomething design student who is hoping to land a job at Forrester Creations.

If the notion of getting "Lost in the Amazon" and finding yourself in a weekly horror movie has any appeal, then by all means set your compass for ABC's The River, the most exciting thing to happen to TV's midseason since, well, Monday's premiere of Smash on NBC. The River is framed as a mock-docu-reality show, following a crew of family members and colleagues searching for a famous TV naturalist (Bruce Greenwood) who went missing on the Amazon six months earlier, in a boat tricked out with cameras like a floating studio.

Comedy veteran Jane Curtin joins CBS' Unforgettable (10/9c) as an unorthodox medical examiner in an episode that finds a serial killer taunting the usually unflappable Carrie. ...
