Worse case scenario: it's Slenderman.
Worser case scenario: it's Tod possessing Slenderman.
Also, I bet you're very confused at what voice to give Slenderman in your head. Considering he doesn't actually talk, or at least not in anything I've ever seen. Because I know I'm having trouble imagining a voice for that speech bubble.
Also if for some strange a weird reason you can't guess (which you probably can), Steve is dressed as Dracula. Doug is probably preparing himself to be dressed as a psycopath, they look just like normal people (and if you didn't get that reference, you have slightly disappointed me).
