There was a lot of subtle foreshadowing in 3B regarding Allison’s death (the red paint splatter, the reinforcement of the code) but I think this is the most important one. It’s Allison, wandering like a ghost, a shadow, staring at her own cold body. Almost like she’s watching her future self.
And then there’s Kate. Allison’s darkness essentially warned Allison, and us as the audience, that Kate was coming back. That she would try and hurt Ally’s friends (she tried to kill Isaac in that dream). But it also warned us that Allison would die. Her darkness wasn’t just visions and dreams created to scare her, it was a warning to everyone what would happen at the end of the season.
Happy 27th Birthday, Tyler Hoechlin! (September 11, 1987)
