The Flash returns with “The Once and Future Flash” on Tuesday, April 25 at 8pm on The CW.
In the present timeline of The Flash, both Mirror Master and Top are incarcerated are out for revenge on the man who locked them up in the first place — and they may not be the only villains that the Flash has to deal with in the future.
This scene is slightly different to the one in the original teaser, which also shows Mirror Master.
In the original, however, Mirror Master is not using his power, but is standing over Barry and kicking him while saying “you’re in for a world of pain.”
