Liam (Jason Gedrick) is determined to expose Vincent (Jay Ryan) for what he is in the upcoming finale of CW's hit series "Beauty and the Beast" season 3.

In "Destined," TV Guide reports that the villain will be pulling all the stops to reveal Cat's (Kristin Kreuk) fiancé as a dangerous beast. Vincent needs to be extra cautious now that he knows what Liam is really after. He has learned that their greatest foe wants to destroy his and Cat's relationship and get the girl for himself. Because of the escalating threat, the couple will have to work together like they never have before.

Liam will do everything in his power to steal Cat, whom he believes to be the reincarnation of his old love Rebecca Reynolds. In actuality, she was Cat's ancestor who lived during the 1800s. Rebecca's journal provided the young woman with a glimpse of what her life was during those times. And just like Cat, she was also involved with a beast until she died.

Meanwhile, Cartermatt believes that the finale is an opportune time for Cat and Vincent to get married. Even amid all the chaos, fans surely will not want to wait for the next summer's installment to see the two profess their vows to each other. As the Liam saga comes to an end, hopefully, Cat and Liam's long engagement will also conclude and then culminate into a wedding.

Last episode, the master plan to take down Liam backfired when the two found the bloody and dead body of Cat's father, Robert (Ted Whittall). He was their ace in the hole in the fight against the villain. Vincent and Cat realized that the only way to defeat Liam was by erasing his memories.

However, they need someone who knew how to handle such a dangerous situation. That was where Robert came in. Although he was certainly not the best parent, Cat acknowledged the fact that he was the only person for the job and they arranged his temporary release from jail. Unfortunately, everything went down the drain when Liam got to him first and killed him.

"Beauty and the Beast" will air on Sept. 10 at 8 p.m. EST on CW.
