Thalia Admos is a Slytherin girl, George Weasley is a Gryffindor, and an older boy. Despite their different houses, George asks Thalia to the Yule Ball, and they start to date slightly after. However, in her fifth year, Umbridge comes along, and so does the opportunity of learning actual defences, so she joins the D.A. However, when George leaves with Fred to start their shop, do they break up? Do they survive the war together? Thalia Adamos belongs to me, everyone else belongs to J.K Rowling
