“And now Barry Allen has reached the starting gate for his last race.

“I know what the plot endgame of next year is.

That’s not a problem,” he said.

“Ironically, it’s set up very succinctly in the season finale for this year.

However, where all the characters end up emotionally, that’s still in flux … What do I want their final goodbyes to this wonderful, loyal audience to be?

That’s what my summer homework is.”

The Flashseason 9 begins filming next month and is currently slated to air in 2023.
