ivy megan hilty smash nbc 'Smash': Did Ivy just become more hated than Ellis?On Monday’s (April 23) episode of “Smash,” Rebecca Duvall (Uma Thurman) is still hanging on as Marilyn Monroe in the Broadway-or-bust musical “Bombshell.” She takes to heart the idea of keeping her enemies close as she befriends Karen (Katharine McPhee) after hearing through the grapevine via Ellis (Jaime Cepero) — naturally — that Derek (Jack Davenport) told Karen she would make a good Marilyn.

Random Bollywood number and Julia’s (Debra Messing) runaway son aside, the real action/drama lies in the last several minutes of the episode. Ellis, demoted to smoothie-making duty for Rebecca, agrees to do Ivy’s (Megan Hilty) evil bidding and sends Karen a text saying she can go home because Julia has the flu. Conniving Ivy is asked to step in and sing Karen’s song, the performance of which brings Eileen (Anjelica Huston) to tears and a round of applause from everyone else. Not one to be outwitted, though, Rebecca sports a wry smile after the performance.

“Derek, suggestion,” she says. “I think Marilyn should sing that song.”

Is Ivy the new Ellis? Or are the two of them together a more evil force than they could ever be on their own? Or is Rebecca actually the most calculating of them all?
