The Flash ended season 2 with a pretty dramatic shake-up, as a grieving Barry Allen, and Iris West (Candice Patton) barely knows who Barry is.
Oh, and somewhere amid all this Barry will also take time out for a musical crossover episode with Supergirl.
As if all that wasn’t enough to deal with, season 3 will also feature a host of other new villains, including The Top, Mirror Master, and Dr. Alchemy.
