The fact that symptoms of Dragonsplague are described so vaguely as pawns being disobedient or unusual means that almost any pawn behavior I haven't seen before is immediately suspect. It's creating a fascinating atmosphere of paranoia.
Like yeah final stages are incredibly obvious red eyes but now if a pawn accidentally zaps me with lightning I think they might have Pawn rabies and will infect my own pawn. I could just look up guaranteed symptoms but I'm enjoying this grey area.
