In this AU, the two have separate bodies, instead of sharing one.
•Bendy spends most of his time with the angels, the Ink Demon would spend most of his time wandering and watching over the mansion
•Would call Sammy over for help if both are being a handful
•The two adore their angels, would hate if anything happens to them
•Sometimes call Tom over, for Alison and him to meet again
•Bendy would be energized, no matter what for them, the Ink Demon would be exhausted.
Unfortunately, I can't think of much for these two.
