You were exploring the Dreamworld facility become stumbling upon a room which had the door open ajar, you opened it letting the light shine in, revealing someone in the middle of the room with a old fashion TV on their head. They then noticed you and looked up and spoke in a soft voice

"..Your not Sara, Are you?.. who are you.?"

It was Oliver! He had gone missing a few weeks after the facility opened*

You told him your name was you, he nodded softly and introduced himself as you helped him up and out of the room, he seemed to be holding a wound on his side
