Not Normal

No one knew exactly what happened.
We all thought it was the Markiplier that everyone knew- playing random horror games and commenting on the scary things that happened. But then, there was that one unknown game. He said that it literally had no title, but played it anyways. After a while, he started changing. His eyes started to get bags underneath them, his skin getting paler. By the third time he played, he even pointed out how horrible he felt and looked. But he kept on playing. During the final episode, he looked his worst- his hands were shaky, and I seriously thought he was going to pass out. Just as he was going to complete the game, the whole recording went black. The video was over.
Two weeks later, no sign of Markiplier. His fellow YouTube friends such as Wade and Jack refused to talk about him. But Felix? Oh, he ranted. About warning Mark not to play it. About how he wasn't... Himself anymore. He said it scared him, the thought of "it" happening to his friend.
A day later, I updated YouTube. Saw the video. It was him, but not him. Everyone said there was no video posted by Markiplier. But I know what I saw. He was sitting in his recording studio, hands folded in front of him, not looking at the camera. The screen wouldn't stop going static. When he glanced up, he looked healthy as ever.
Almost.
His usually-brown eyes were pitch black, the whites of his eyes almost bloodshot. Skin- pale as ever. Bags under his eyes. He looked straight at the camera, a demonic look on his face, putting a finger to his lips.
"Ssshh."
Then, gone. The video disappeared completely from existence, no proof that it was ever there. Talk about freaky.
Then, the texts started. Random, unknown texts that made it seem like he knew where I was at all times. It scared me.
It got worse when he appeared suddenly in my room one night.
"Hello. My name is Darkiplier. You can call me Dark."
I never looked at the Googiplier video the same way again.
