This week on Revenge: reintroducing Emily Thorne, cat burglar extraordinaire.

Jack Is Feeling Optimistic In 'Bait' Sneak Peek, Will Jack & Emily Get Together On 'Revenge'?

A little mishap at LeMarchal Media, however, could have the revenge artist contemplating an early retirement for her cat suit.

Despite Nolan's (Gabriel Mann) expert security hacking and Emily's years of experience, Margaux (Karine Vanasse) may outwit the duo during "Bait." Carefully repelling down a skyscraper and Mission: Impossible-ing your way through the halls will do you no good if your nemesis has positioned armed guards directly in front of your alleged target (see video here).

Two New 'Revenge' Titles Revealed, What's Next for Emily Thorne?

Luckily for Ems, she won't be the one who walks in on the trap - at least not yet. A certain former psych ward patient will drop by instead (see photo above).

The CEO and mother-to-be is raising her blood pressure (think of the baby!) in an effort to take down those she believes responsible for her Daniel's (Josh Bowman) death. If Margaux does release the info she has on Em and Jack (Nick Wechsler), the repercussions could be catastrophic.

"Should she release this information? And if so, how should she do it?" Vanasse explained to TV Line. "Everyone has experienced so much loss because of this girl, so Margaux's like, 'We have to stop her.'"

Find out if Emily will fall into Margaux's trap when Revenge airs Sunday at 10 p.m. ET on ABC.
