They already started working on season 5 after episode 4 released. Oh absolutely, but working on something doesn't necessarily mean they had it planned before season 4 ended, that's what I meant. As I mentionned, Season 4 ended in a way completely unlike any other endings previously : Without any hint on what comes next Episode 4 or Season 4? Season 4, I didn't really spot any sequel hook after the finale in episode 6, nor much of any hints during the whole season, beside maybe one mention that Jormag and Primordus were rousing again, which I found odd, as both had been "addressed" before. I meant, the person you answered stated Episode 4 (of Season 4). Or was it a typo?
