I'm Shell and I'm bringing in Gwen, Prissy's younger sister and the last remaining Weasley twin. While Gwen is stunned that Prissy came back to the family during the battle of Hogwarts she still think's that she is a prat/git but treats her better for seeing the light at the end of the tunnel. Since they have different career path's I can see them bumping heads and not getting along overly well but in light of everything that's happened I can see Gwen attempting to get to know her older sister better.
