Beauty and the Beast Midseason Finale Sneak Peek: Will Vincent Kill Catherine's Father? Watch and Find Out!

Exclusive! The CW drama closes out its fall run of episode tonight at 9 p.m. with Cat making decision that will change her relationship for good

Watch out Catherine (Kristin Kreuk), you may just be losing your love and your father tonight!

In Beauty and the Beast's midseason finale, airing at 9 p.m. on the CW, Lady Beast Tori (Amber Skye Noyes) will push Vincent (Jay Ryan) to take out Reynolds (Ted Whittall), the man who had been controlling him for months. Too bad that man just so happens to be his love Catherine's father. Catherine and Vincent, redefining the term "it's complicated" since 2012.

But will Vincent actually kill Reynolds? We've got an exclusive sneak peek at tonight's midseason finale, titled "Man or Beast?," which features Tori trying to persuade Vincent, whom she killed in last week's episode, to eliminate Reynolds for good...

"You have to choose who you want to be. Not based on the past, but on the future," Tori tells Vincent. "And the best way to do that is to stop fighting your inner nature. Our inner nature."

Then Tori really goes for it, trying to sell Vincent on taking Reynolds down harder than a used cars salesman pushing a crap-mobile on an unsuspecting customer. "You saved me, You opened my eyes to a world I could've never imagined. You showed me what I was born to be. Because of that, I feel free. Let me return the favor," she says.

But will Vincent actually be persuaded by Tori? Or will Cat make a move before the Beasties have a chance to strike?

Well, the episode description probably won't provide much comfort for VinCat fans: "Vincent and Cat find themselves at odds on how to deal with Agent Reynolds, which forces Vincent to wonder if he is more beast than man. Cat makes a drastic move that will forever change her relationship with Vincent."

Beauty and the Beast's midseason finale airs at 9 p.m. on the CW.
