Shea Allen (portrayed by Gina Holden) is Trish's big sister and the Matron of Honor. From the outside, she appears to have it all - a great husband, a beautiful daughter and all the money in the world. But nothing is as it seems. There are problems in her marriage and her daughter Madison is acting out. The stress of keeping up appearances has Shea trapped in a life she never wanted for herself. Shea is one of the survivors on Harper's Island.
