If the hand is just a fake, then maybe my crazy "Hit the Road really takes place after the Telltale games" theory could work after all! There's some evidence towards this:
-Stinky's has been Stinky's since 1980 at least, but in HtR it was called Really Bad Food. Maybe Girl Stinky sold the shop after making her adhesive/zombie hand spray.
-Bosco is unseen in HtR and referred to as "Old Man Bosco". He might've aged a bit since Season 2. Also, Momma Bosco's soul could've returned to her body somehow since she didn't have her token, and then helped Bosco run the shop, which explains why "Baby Needs" are once again sold there.
-The Esperanto Bookstore isn't in HtR, Bosco's is right next to the office, like in Season 2.
^ Thanks for reading that.
