Your parents are hunters, although they tried to have a normal, apple pie life when they had kids, it didnβt work out. So instead of moving around like how Sam and Dean were raised, they stayed in one spot and hunt monsters in the same city and neighboring cities and small towns nearby but they never leave the state.
Sam and Dean were hunting a vampire nest and needed help so they called Bobby who told them your parents lived there. They recognized your parents namesβ and remembered them because John would hunt with them time to time, they never knew they had four kids though.
After being introduced, Sam and Dean were invited to stay at your house in the spare rooms until they killed the vamps nest. They did not think you or your 3 older siblings, Alexis, Rudy and Roy, were hunters.
Sam, Dean and your parents (Angelica and Andrew), sat at the dinner table, eating breakfast at 7 A.M. while you got ready for your pottery classes since school is canceled, Alexis got ready for work and your brothers got ready for work too.
βSoβ¦β Dean said, trying to break the awkwardness and quiet of the table.
βYou two still hunt?β Sam finished, Dean ate a sausage while Sam spoke, both of them looking at your parents.
