The first encounter of Seek is when its eyes appear in the rooms before Seek's appearance, (referred to as Seek's crescendo) foreshadowing the chase sequence. The first door you begin to see the eyes, the chase sequence will begin at the 4th door (i.e. seeing eyes at door 35 will cause the chase to occur at door 39). Said eyes will continue to increase in numbers as players approach the chase sequence before abruptly stopping on the pre-generated hallway.
