It was only a brief moment, but it could be argued that the most shocking WTF moment of this whole episode involved Martin Stein beating down a Space Pirate. Whenever weve seen Stein so far, be it in Legends of Tomorrow or The Flash, hes pretty much never, ever got physical with anyone, instead using his brain to take down foes and tackle problems. Here, though, with Stein channeling his dreams of being a Space Ranger, he ends up getting his rescue mission rumbled by a gnarly-looking Space Pirate. The pair would end up off-screen and behind a conveniently placed door, but Stein would soon emerge looking proud as punch for apparently laying a beatdown on his opponent. Clearly Professor Stein is a bit more of a badass than most give him credit for.
