Levi has pegged the Doctor as someone Good At Talking by now so he'd probably try to seek his help for reasoning with the reluctant Forest Talkers! Alternatively he could help with building the defenses or yank him out of trying to put himself in harm's way or something.

I was also wondering if you wanted to do anything with their Scouting Initiative or whatever it ends up being? :') Since they agreed on it I assume they've probably been trekking into the wilds in various directions and meeting up every now and then to compare their findings (I'm fine handwaving that unless it looks like a fun thread might come out of it), but should we maybe also ask the mods if they might run into anything of note?
