While attending San Diego Comic-Con, The Flash stars Grant Gustin and Candice Patton revealed that Barry and Iris will keep the scarlet speedster’s disappearance a secret for a couple of episodes before telling the team.
The Monitor will be paying them a little visit to let them know that “Barry Allen has to die.”
It’s been revealed that Barry and Iris will discover that the speedster will die in “Crisis on Infinite Earths” at the end of the Season 6 premiere, “Into the Void.”
That makes sense, especially considering the emotional toll the news will take on the couple who will also be dealing with the grief of losing their daughter.
