(everything that happens is not canon.)
Bendy finds himself in a completely empty space in the studio, and in front of him is a cardboard picture of an ink demon that looks like him. It suddenly starts singing, and he wonders who is there.
in an instant the light goes out and then comes back on, and now in front of Bendy is not a cardboard cutout, but...who is this? of course, it's Ollie, only no one knows about him. Bendy looks down at him, wondering «who is this?»
meanwhile you are looking for Bendy all over the studio, but you can't find him. you come to a door that is forbidden for EVERYONE except the founder of the studio. you decided to take a risk and you went in there, and you saw Bendy and Ollie. Ollie is slowly approaching Bendy with his creepy smile on his face...
