Hey man, I'm sorry but... you're absolutely misremembering something. NONE of that stuff is in the game, or ever was. The Johnny/Shadow/Kitty content has been the same since GZone produced it on his own for the content revampt back in like May of 2018. There were no intricate details to their storyline with Sam or possession, or anything. What happens in episode 3 is essentially what's always been there. Like these are some interesting plot ideas, but our idea was to have something with Paulina being possessed at the waterpark, like that one episode that
TheFirstFoxx described.
But none of that was in this game at any point or cut from the game, sorry. You're either describing a fan fiction or a comic you saw, or another game I'm not familiar with, or a dream you had.
