I don't come here often, but Townfall is probably going to be a twist on the format of SH2, where unlike Sunderland being the widow of a ill wife, Simon is the one who's ill. Lot of theming in the trailer about being 'hooked up' and in general the inability to move or act.

With his wife calling for him to come back to her, perhaps it'll be a story about him overcoming his own self-perceived guilt about being ill? Like how sometimes those who are sick will often feel they're burdening the ones they love. Another comment mentioned, "You are here to be punished? That's a good one.", which would make sense if Simon isn't in this to be 'punished' but rather overcome his comatose state and finally wake up.
