Want to know the SWAT season 4 episode 15 return date over at CBS, or some additional insight on what could be coming next?. There are a few different things worth getting into here, but let’s start with the news that will probably bum a ton of people out: We’re about to enter another hiatus. It’s not some enormous, devastating one, but a hiatus nonetheless. The series is currently poised to return on Wednesday, May 5, with the great news here being that this is when all of the breaks will most likely be over. Won’t it be nice to be at a point where there are just frequent new episodes again? You’ll likely get new installments from there until the finale near the end of next month.
