'The Flash' season 7 trailer sees Barry Allen (played by Grant Gustin) losing his power, endangering the life of his beloved wife Iris West (Candice Patton). Iris has a doppelganger who describes herself as a 'product of Iris' broken mind. Thus, if Barry Allen does not regain his power in time, he has a high chance that his wife Iris could turn crazy. Did Joe help Barry give him artifical speed, is something that will be left for the movie. Also, Barry comes across a man capable of powers like him in Speed Force (played by Andy Mientus, who was originally Hartlety Rathaway).
