This should be an episode that satisfies many out there looking for some sort of closure into what has been a long-running, at-times complicated story. There are twists aplenty, and there is also a great Jane moment where you once again realize just how smart the man really is. While the site’s Matt Mitovich claims that there is possibly a mystery that will still linger from this episode, that is disputed by other reporters. (END)
