Not gonna lie, he already makes a creepy character in the series due to his creepy smile, it would be cool if he could be a new character in HN2 maybe he could be an AI that can help us somehow or maybe be a suspicious character like all the others. I'm not sure where he'd be, maybe he'd have a place near the Raven Brooks Middle School if you guys do intend to make the DLC maps part of the main map, or something like that idk. Not sure how he'd be involved with the story. He could hide something "flammable" ||that one was a joke||. I don't know what he could hide.
EDIT: But also, if you guys do plan on updating Back to School you guys should add his classroom in the game maybe it could be the blocked off boarded up room or something.
