One of the biggest draws of Telltale’s take on the Batman universe is that it has spent its first two seasons flipping Bat-universe convention on its head. Between Vicki Vale’s heel turn and Thomas Wayne’s criminal past, Telltale has not been afraid to flip the script in Gotham City. Perhaps the biggest payoff promised for ‘Same Stitch’, the finale of Batman: The Enemy Within, was that John Doe would finally become The Joker, just as we’ve been waiting for all season. With it, John could take his place as either your arch-nemesis or... your partner. While The Enemy Within never quite fully commits to that reversal, both the episode and the season are memorable for leaving scars on its stars – both physical and emotional.
