Arianna Gilbert (Vampire Diaries)

Arianna Gilbert has felt like she's drowning ever since her parents died. People seem to think only her twin sister, Elena, is struggling. After all, Elena is the good twin. Arianna is just the fun one who always gets herself into trouble. People figure she can handle things by herself just fine. Can't she?
But both girls' lives are changed when the Salvatore brothers move to town. Elena has Stefan but Arianna has her eyes on Damon. But are Damon's feelings for her real? Or is she just a distraction until he can get Katherine back?
