you were Mark's recently adopted kid, which was actually pretty cool, you were still not quite used to calling him dad or even father yet though, but he was fine with it, all he wanted was for you to be comfortable around him really.
one thing he never quite told you though, was about the...'alter egos' that lived in his mind, for example...Darkiplier. Though naturally, with dark being himself, he didn't want mark to keep him hidden away, and now that he had a kid? Oh he'd have to make himself known to them at some point...maybe even try to have them like him more than mark.
so tonight, as per usual you weren't quite sleeping well, so you went to get some water, but when you came back to your room, you saw a strange figure in a white suit, standing by your window and seemingly looking at some stuff you had on the windowsill. At first you assumed it was mark, but when the man turned towards you he looked a bit...off, gray skin, black hair, black eyes, just monochrome in general. Though the oddest thing so far was the almost glitching red and blue outline around him.
