"We did," said Weisman. "For starters, Season 1, we had 26 episodes. We had an arc for the season, but we were introducing characters, concepts, a world. So I think there's a nice drive to Season 1, but it's absolutely relaxed compared to Season 2. Season 2, we only have 20 episodes. We have an intense story to tell -- really, in some ways, a single story. Each episode still stands alone and tells its own discrete adventure, but it's all part of the whole. And it really plays like a novel. It's got a drive to it that's just exponentially more intense, with more momentum. And we introduce a ton of new characters in Season 2, but this time you're going to have to get to know them on the fly because we are just pushing through to get to the end of this big, big story." -- Producers Greg Weisman
