Vincent (Jay Ryan) and Cat (Kristin Kreuk) will finally team up once again to hunt down this season's bad guy, Liam (Jason Gedrick). The duo will do anything to stop him from hurting more people in this week's episode of "Beauty and the Beast," titled "Patient X."

According to the official synopsis, after the couple's botched wedding in last week's episode and Cat's reluctance to help in tracking beasts, this week will see her back in action with Vincent to stop Liam once and for all.

Vincent and Cat's highly anticipated wedding was halted as Juliana escaped prison and Liam attacked their wedding ceremony, killing Juliana in the process.

The events of last week were too much for Cat that she decides to throw in the towel and stop any investigations on the beast. She knows that the only way the two of them can get married and be happy is for them to stop chasing these beasts.

Cat's decision leaves Vincent hanging, as he is determined to bring Liam to justice and end his reign of terror.

Vincent knows he cant do it on his own and he tries to convince Cat to help him. He succeeds and Cat is once again ready to risk everything to capture Juliana's killer and end Liam's evil ways.

In their mission to find Liam, the two will stumble upon information that leads to a certain Patient X, which they might be able to use to capture the beast.

While Cat and Vincent are busy chasing the trail of Liam, JT (Austin Basis) will face a few challenges of his own as he and ex-girlfriend Tess (Nina Lisandrello) try to work together to determine if he is already serum-free, noted Carter Matt.

It seems that JT has already cured himself but this week's episode will show that he is still exhibiting symptoms.

With Cat and Vincent on the hunt and JT and Tess facing uncertainty, it might just be a matter of time before Liam shows himself to wreak havoc and chaos once again to prevent Vincent and Cat from having their happily ever after.

The season is on its last few episodes and things are set to get more exciting and dramatic for the stars of "Beauty and the Beast."

The show airs every Thursday on The CW with the episode "Patient X" slated for August 13.
