Yes it is a Jughead accidentally freed an incubus and wowza is Betty hungry but hey that’s the danger you have to accept when handling old valuable books is your job fic because I have no impulse control and my subconscious is a wild thing. The rest coming... not soon but eventually. My very late entry to Tricks and Treats of Riverdale. 

It’s an and then they were roommates ghost style.

Theme 1: Jughead Jones followed the destiny laid out by the town’s expecations and it led him right into the slammer. Now out and determined for it to stay that way, he works construction by day and labors over his novel at night. When his team lands a job doing repairs to The Cathedral of Saint John, Jughead sleeps in the abandoned Church. Upon his sleepy snooping, he stumbles across a cranky Gargoyle who wants some peace and quiet. Betty really isn’t a bad roommate, and soon she means much more. Destiny seems to have different plans for Jughead Jones than he thought.  

Ancient Being: Gargoyle!Betty Will upload an in-depth character edit for this au’s Jug in a minute. The territory Betty guards is the Cathedral of Saint John, the Divine in NY. Feel free to write something inspired by this!!! Please tag or message me if you do!!!! My unfinished au is really specific and I would love to see more Gargoyle!Betty.
