Fan Casting Flash in The Flash: Chaos Effect

Barry has had to deal with a personal loss before with the death of his mother, Nora Allen, in an accident, something that also motivated him to move on despite everything. Joe's case was a little different, as it brought together Barry's regret of not having really managed to save him...but could he? This questioning leads to a experiment to test this, with Flash rewinding time to the right moment. But as he would discover, the Multiverse doesn't usually differentiate good intentions from others before giving its own answer.
