The Flash Season 3: 10 Big Questions That Must Be Answered
5. How Does Wally Get His Powers?
Much like Jesse Wells, the arrival of Wally West last year brought with it the promise of speedster powers, and again it appeared as though the particle accelerator explosion would be how/when it happened.
It wasn't to be, but with Wally we do now have confirmation that he'll be suiting up and developing superspeed in Season 3, having already seen him in costume as Kid Flash.
However, based on the trailer, we're seeing him as Kid Flash because of Flashpoint, which means a) we don't know how he got his powers, and b) whether they'll find a way of him being Kid Flash when things eventually return to normal.
