This means she helped Joyce get back her youngest brother from the upside down and helped her twin, his new 'girlfriend' and Steve (Whos always been a prick to Jonathon so I dont know why he's helping?). That's when she goes to the pool with her group of friends(Lulu Wheeler older sister to Mike and Grace (Guacamole) older sister of Dustin.) When she spots a certain Hardgrove. At the lifeguard chair and becomes close to him in a matter of days. Will they be able to get together while Billy is getting abused every day and worrying if he introduces Lilly to his father the same will happen to her? And while Lilly is trying to be there for her brother and Billy at the same time? Dun Dun Dun. This fic was made for my obsessed Billy friend.
