So thats it for now for Martin Stein and Jefferson Jackson. They make their plans known to visit an old friend of Steins to help them with their bonding process, with them definitely to be a part of DCs Legends of Tomorrow and likely to turn up again in The Flash before the season comes to a close. Regardless, their absence is a relatively permanent one for now. As such, its a little strange to see Firestorm just fly off into the ether with not even a suitcase in sight. Heres hoping that theyd previously arranged for at least a change of clothes to be shipped out to their new locale.
