'Beauty and the Beast': Cat's Sister Returns at the Worst Time (Exclusive Video)

Catherine's sister is back on Beauty and the Beast.

Heather (Nicole Gale Anderson) returns on Monday's episode of The CW drama, but her timing couldn't be worse. In an exclusive clip which The Hollywood Reporter debuts, Cat (Kristin Kreuk) is surprised by her sister's sudden reappearance. After all, Cat's being spied on by her very own precinct.

"What are you doing ... here ... in New York ... right now?" an out-of-breath Cat asks Heather. "Aren't you happy to see me?" her sister asks, slight disappointment beginning to show.

Heather's main reason for her unannounced visit is to tell her about her recent engagement, but before she can break the news, Cat gets out of the situation by lying about having to get laundry from the roof. When will Heather break the news of her engagement?

Beauty and the Beast airs Mondays at 9 p.m. on The CW.
