WARNING: This episode may contain spoilers for SWAT season 3 episode 21. Read at your own risk.

The release date of SWAT season 3 episode 21 is delayed due to several reasons. The episode is coming later this month, so viewers may need to wait for a little while. But despite the delay, there are still intense and interesting stories coming given that the episode serves as the season finale.

Several shows from different networks wrapped up their production due to COVID-19 concerns. But for SWAT, the series was able to film the majority of the season since it started early. The show filmed 21 episodes of their originally 22-episode order. So, SWAT season 3 episode 21 now serves as the finale.

However, viewers may need to wait since it may not be arriving anytime soon. The reason for the delay is that the SEAL Team season 3 finale is airing next week, May 6. Then, the series will not also air on May 13 because of the Survivor finale and reunion show. The series is returning on the third Wednesday of the month.

No further details about SWAT season 3 episode 21 have been revealed. Yet, it may leave some cliffhanger since the episode is close to the original season finale. There could be big reveals and unexpected twists and turns moving forward.

Right now, however, there is no official announcement from CBS about the future of the series. The network hasn't yet officially renewed the Shemar Moore-led series for season 4. Despite the uncertainties, many believe the series is coming back to deliver more stories in the future.

When it comes to the ratings, season 3 has averaged a 0.6 rating in the 18-49 demographic and about 3.9 million live viewers. These numbers dropped compared to season 2, but there's still hope here. Reportedly, the series is comparable to other CBS' programs at 10 PM Eastern timeslots across the board.

In addition, the series' international popularity, DVR performance, and the presence of Moore as the lead character could be enough to consider the show having another season. Furthermore, unlike other networks, CBS doesn't have many cancelations over the previous years.

There are still a lot of stories to tell moving forward. The characters have been dealing through a lot of struggles on a regular basis. So, it's exciting to see how they could deal with their everyday lives, both personally and professionally.

SWAT season 3 episode 21 will be airing on Wednesday night, May 20, on CBS.
