That Saint Electric poster is doing numbers again and it always gets tagged as Sid haha. It was never meant to be him (it was drawn suuuper early on in the show before we had much of an idea of who the radio presenter was) though, just a propaganda poster praising the Saint.
I’ve generally got very little coming up with headcanons for what podcast characters look like because it can change so much in my head and The Silt Verses especially has a lot of fodder for just drawing the feeling of a thing that’s going on.
