jealous weasley?| George Weasley x O.C

This story takes place in Alekjandrya Diggory's Fifth year. She is Cedric Diggory younger sister and was sorted into Gryffindor. She is in the same year as Fred and George Weasley. The three of them have been inseparable since there the first year. George and Alekjandrya have been together since the beginning of their fourth year. It's just another normal year at Hogwarts until Alex has well another Quidditch incident.

Note:
I know that Oliver Wood and Katie Bell are not in the same year as the Weasley twins but for this fanfiction they are. Just clearing something up.
