you can clearly see how much S2 changed even not too long before its release
remember this person from the first S2 promotional picture? they were too small to be Jane but they look to have short hair like her. somewhere along the line this person got cut, and who knows if it was to make room for a character return like Kenny’s.
I also believe the 400 Days characters were supposed to have a bigger role. That’s why Eddie and a few 400 Days PCs were on the title slide for Episode 4 (the PCs were shadowed out and harder to see, but you can clearly tell some of them, like Vince and Wyatt). That’s also why the title picture has little to no connection with the actual episode.
I have to wonder just how much got changed, and if maybe that’s why this season’s been kind of a mess.
