In this AU, Jared Padalecki has a younger sister named Caroline Louise Padalecki. She's 26 years old born in June 17th and everyone from the Supernatural cast absolutely adores her (Jensen is pretty much her brother as well as one could imagine). So much so that she's had several small roles in the show but even with the small roles she held, she still was loved by the fandom.
And yes, she lived Jared and Gen, as well as the two cute little boys that she called her nephews. Jared and Gen didn't mind her living with them one single bit. She helped out around the house, helped with the boys, and overall she was a joy to be around.
But what happens when the show does a long awaited crossover episode with The Vampire Diaries and she somehow manages to capture the attention of Damon Salvatore himself? Ian Somerhalder? Well I guess only time could tell.
"Wait so you mean to tell me that you're Jared's sister? As in Jared Padalecki?" ~Ian
"The one and only! But I like to see myself as the better looking Padalecki." ~Caroline
