Tyler is released from Fireweed, a juvenile center where he was sent after killing their mother in self-defense. Alyson picks him up, and they return to their childhood home in Delos Crossing, Alaska. As they begin sorting through the house, they rediscover their supernatural bond, the ability to communicate through telepathic communication that lets them relive shared memories. The two start questioning what really happened the night their mother died.

So uhh, this is awkward huh?
The twins investigate Mary-Ann’s past, confronting people like Tessa and Tom Vecchi, who were close to her. They uncover financial struggles, emotional turmoil, and hints that Mary-Ann may have been trying to protect Tyler, not harm him. Their bond is tested as they face conflicting memories and emotional revelations.

Tessa will never know
The final chapter reveals the deeper motivations behind Mary-Ann’s actions and the truth about the twins’ father. Depending on player choices, the twins either grow closer or drift apart. The story ends with them deciding what to do with their childhood home-either selling it or starting anew.
