You walk through a Unitologist chapel to get to Isaac Clarke, you stand among the vents and pipes of the matin. corridors, when you hear it, Clarke shouting

you whip around and start running to where you heard the voice

Isaac: "YOU'RE NOT NICOLE, YOU ARENT REALLY HERE!"

you finally arrive and see Isaac wrestling an apparition of his dead girlfriend trying to stab him with a needle

Apparition Nicole: "YOU'RE HURTING ME, ISAAC."

the spirit screams in a static malicious and sarcastic voice, beams of light emit from her mouth and eye holes, her uniform drenched in blood, her pale skin drips blood
