I'm in love with a killer

Who is he?

It was a dark day today, you are in your room huddled close to your computer screen. Wrapped in a soft blanket while you enjoyed a jacksepticeye video. The rain tapped on the window as the video slowed down. You look up and see the video has returned to normal, then it happens again this time you hear Sean laugh demonically. His face... Is different? Then your computer shuts off and something is behind you, but nothing is there... You think to yourself "what the hell is going on?" You shudder, then turn back to your computer and try to turn it back on. You sit and wait as it loads.
