I’m gonna send some non angst stuff. MC finds their brother and his interactions with the gang are basically pranks, heavy sarcasm, and terrible puns. Tonks and Tulip love him and pull the most elaborate pranks with him! MC is just relieved that they get along, until they are on the receiving end of one of these pranks. Then a full out war prank between the siblings is unleashed and NO ONE is ready. Only time will tell if anyone makes it out alive.
Jay after finding her brother:
"actually put him back"
"I liked him better when he was just a memory"
"My brother is nice? Yeah, he had years to work on himself inside the painting."
"Oh you like my brother? Keep him. No like actually hold onto him so he doesn't disappear again"
Jay's revenge prank: disappears for 7 years
