"Beauty and the Beast" season 4 is coming to an end and there are speculations that the season finale will see the death of Vincent and Catherine.

Titled "Au Revoir," episode 13 is the final episode of the current season. The promo video for the episode suggests that Vincent and Catherine may die, but nothing is official just yet.

It can be recalled that in the season 3 finale, Vincent and Catherine moved in together to start a new life, away from the people from their past. However, things did not go smoothly for them as they kept being blamed time and again for things that they did not commit. In the previous episode, Vincent was once again interrogated for an attack he was not responsible for. Some speculate that the upcoming episode will see him reveal the truth to the world.

"Vincent and Cat are willing to make the ultimate sacrifice to stop an attack and rid the world of beast makers once and for all," reads the synopsis for the episode. While there is a chance that they will succeed in their goal, the synopsis hints that the two characters might end up having to sacrifice themselves.

The promo for the finale shows Vincent and Catherine comforting each other. One scene shows them driving recklessly, as if trying to prevent something bad from happening. The video also shows massive firing all over the town.

"Beauty and the Beast" season 4, episode 13 airs on September 15 on The CW.
