It's the one with the furries that either kill you or assimilate you. It's as though it were made for me. Seriously though, this was a great one, worthy of being the finale of the original series; it's a well-constructed mediation on violence and survival and what that turns people into, on what 'home' means, on the strength that pacifism requires. It's also about Lisa Bowerman as Ace's furry girlfriend, the absolute cherry on top of this magnificent finale.
