"Beauty and the Beast" season 3 is constantly proving that Vincent can never simply sit back and enjoy the feeling of getting hitched. The upcoming episode titled "Chasing Ghosts" is no exception. In this installment, the trying to be normal lover boy's bachelor party courts an uninvited guest.

JT had all the right intentions when he threw the surprise party for Vincent. He didn't take into account the possibility that a brooding sniper will join the get-together because why would there be in the first place. Unfortunately, this is the very thing that happens.

As it turns out, the mysterious hitman was present to take out anyone who gets in the way of the superhuman experiments and by anyone that means Vincent and Cat. "Beauty and the Beast" season 3 will show the lengths Vincent will go to eliminate anyone that thwarts his plans.

Will this incident be enough for the couple to call off their wedding? In the previous "Beauty and the Beast" season 3 episode, Vincent discovered that he can control his rage simply by reminding himself of his love for Cat and Cat's love for him.

He was successful in killing Bob, which led to the passing away of his wife, Carol (who stopped her own heartbeat) thus saving Cat from danger. Despite this new breakthrough in their relationship, the problems just don't stop there, unfortunately.

As this bachelor party gone wrong goes full-throttle, Cat will be busy with her bridal shower Heather arranged for her (her family came to town just to be there) but not as much as she is with visiting and getting help from his father in prison.

It remains to be seen how Vincent will take out this murderous gatecrasher. In the trailer, Cat's family showing up seems to be bigger problem to him than the superhuman assassin. "Beauty and the Beast" season 3 episode 6 "Chasing Ghosts" airs July 16.
