Sebastian's epiphany kindles when he regains confidence in his memories. After The Evil Within, Mobius gaslit him and undermined his credibility. No one believed him, and Sebastian internalized his memories as symptoms of possible mental illness. He believed that they happened, but the world did not support his belief.

Positive or negative verification of experiences impacts self-image. Sebastian's self-doubt forced him to rely upon his own memories for evidence of his experience, which, as we saw in his re-enactment of the house fire, he revised into a feedback loop of self-criticism. Sebastian re-enacts those altered memories through each encounter with Anima, relying on strategies learned from the player, his source of distortion.

The fever breaks after his final escape. His dream vision of Myra taught him to challenge his guilt with evidence and context. He finds evidence that proves Mobius's deceit. Sebastian's self-doubt dissipates when he can finally view Beacon, not as a memory, but as an objective event — something that happened to him rather than something he did to himself.

Sebastian rejects more than Mobius's version of events. He starts to reject his dependency on the player. The player's memories of The Evil Within have filled his head after each Anima encounter, forcing him away from further contact with his Other. He now pushes those memories outside his head.

At 345 Cedar, Sebastian walked into the television's world. He stepped into the metanarrative — into his role as the player's character. Now, rather than internalize his role as a videogame character without agency, he expels the player and sees our memories exactly as we had: flat images of light. Without the player's drag, he can finally reach his Other.
