Alright, while this isn’t a place for spoilers I just want to say: no, Connie is not banned from saving the world. Just in case there was anyone out there afraid that something like that might happen.
Other than that, there were a lot of people who watched the second preview and got the right idea. Again, no spoilers here, but if you’re willing to follow a link that will spoil the episode… Well, it’s starting. If that’s not important lore information, then this show doesn’t have much of a storyline at all.
