– Kuriakin, with his dying breath
Professor Kuriakin first appears on television during the Fugitive chapter, speaking about the ancient Mayan civiliazation. Lucas sees this as a fugitive, hiding out in his ex-girlfriend's apartment, and desperate for answers, visits Kuriakin at the Museum under the guise of a journalist conducting an interview.
There, Kuriakin speaks of human sacrifices, gods and of an oracle. It's all strikingly similar to Lucas' situation, such as the Mayan god, Quechnitian being a serpent with two heads, an image which Lucas had carved onto his forearms while under possession. And of an oracle who performs human sacrifices, using a proxy to commit the deed of stabbing the victim into the heart three times.
Depending on the players actions, Kuriakin may become suspicious of Lucas and fetch a nearby guard or believe Lucas' story and trust him, and will either stay behind or go with him into the parking lot where he will die after being pushed onto the ground and out of the way of a rushing vehicle. His dying breath is spent on telling Lucas about the Indigo Child.
- Lucas uses the fake name "John Cunningham" when meeting Kuriakin.
