The Flash Season 2: 11 Big Questions We're Asking After 'Trajectory'
4. How Many More Speedsters Can We Expect?
Barry Allen, Eobard Thawne, Jay Garrick/Zoom, and now Trajectory.
We've had plenty of speedsters on the show so far, but there's still scope for more. We're almost certainly going to get at least two more, in the form of Wally West and Jesse Quick, unless there's a major rug-pull where their characters are concerned.
Outside of those, well they could introduce as many speedsters, both heroic and villainous, as they wanted. Johnny Quick, Max Mercury, Bart Allen, Savitar, Black Flash... there's a great wealth of speedsters out there, and we'll surely see a few more as the series continues, but Wally and Jesse would be a good place to start.
