Why would the witness protection program allow the witness to be in a reality show?
The whole show is absurd and surreal. Just because it is live action doesn't mean it is realistic, nor does it have to be realistic. In fact, that's why Delocated works on Adult Swim, it is so, for lack of better words, "out there." My favorite part about the show is that while it is so absurd and crazy, it is very dry in execution. This dry humor almost makes it even crazier. Then you add on Sergei and an expanded and focused plot (Thanks to the 30 minute runtime), and the show just gets better. Season 2 added so much more depth to the show. In a way, it kind of saved it. It certainly has more fans now than it did before.
It may not have massive viewer numbers, but they would be foolish to get rid of Delocated. As of right now, It's only getting better.
