"That's one of my favorite things about this show and that was important to me," Gellar said. "I love the mysteries of it. As an audience, I know you want answers, and so that's one of the fun things about the show is we do answer a lot of the questions very quickly. Unfortunately, [we] bring up five more questions."
One of those tantalizing questions revolves around Siobhan Martin, Bridget Kelly's twin sister in which whom Gellar plays both roles. While Bridget has assumed her sister's identity due to trouble with the mob, Siobhan's agenda has been shrouded in secrecy while her true intentions have yet to be revealed. Siobhan's husband, Andrew Martin (Gruffudd), isn't squeaky clean either, an interesting tidbit that only spins the web of deceit even more in this dramatic series.
