Yeah, Clone standalone would be Quality Cut. Deserter is the ‘core’ clone individuality episode, I think, so if you’re only including one such episode I think that’s the one. But bringing a few good ones together on the same theme might help sell the concept and allow you to highlight the best moments without needing deep dives, so that when that thread starts getting pulled more later, you’re lined up for it, without having had to take focus off the main plots of the show for too long. The secondary feature of such an anthology would be to pull Rex into more focus and allow him to become more of a main character, a little further into the show than the beginning, when you’re ready to follow someone new.
