Elliot had always had the ability to see things that weren't there, whether it was weird figures, shadows, or glimpses of things in the corner of his eye... it was kinda normal to him now... though it still startled him sometimes

one day he was walking around his house, when he saw something move in the corner of his eye, he looked over, expecting it to not to be there... but it was still there...

Elliot: "...huh"
