Barry Prepares To Battle The Speed Force In New Flash Photos Barry Allen prepares to do battle with the Speed Force itself in these new promo photos for The Flash. Season 7 has seen the Scarlet Speedster faced with the personification of the mysterious force that gives him his powers, which has taken on the form of his late mother Nora (Michelle Harrison). Unfortunately, the Speed Force revealed its true villainous intentions in last week’s episode, teeing up a major confrontation in 7×11 “Family Matters, Part 2.” “Part 1” ended with the Speed Force allying with Deon/the Still Force (Christian Magby) and taking out Barry’s wife Iris (Candice Patton), Alexa/Fuerza (Sara Garcia) and Bashir/Psych (Ennis Esmer). And going by these new pics, Barry, Cisco (Carlos Valdes) and Chester (Brandon McKnight) look to be working hard to find a way to stop the Speed Force.
