I was thinking about it and I think Jonathan Sims was kind of conditioned from the beginning to believe he couldn’t save anyone. In his nightmares, it’s mentioned that he tried so hard for so long to help them, but all he could ever do was watch. So when the world ends and he sees all these people trapped in domains, he doesn’t even consider trying to get people out, because he doesn’t think he can, or if he can, it’s not like he can keep them out. Turns out he technically isn’t even protecting Martin, the Eye is. And we see with Georgie and Melanie that it’s only a matter of time before people get grabbed again. I think it would be really interesting to explore an au where he teams up with Georgie and Melanie instead of following the course laid out for him and they try to rescue people and free entire domains together.
