“People expect it to be a straight line to finding one another and living happily ever after — and that may not be the case,” Moore told Entertainment Weekly of the series’ upcoming flashbacks to her and Jack’s first date and past love story.

But don’t despair. Creator Dan Fogelman promises that season three will feel lighter than season two. (Thank goodness! We were going broke with all the tissues we had to buy.)

“There’s humor and love and levity after a very heavy season which I always like when we do,” Fogelman told The Wrap. “And then… some wallops. It’s our most ambitious season. It’s going to pack a great deal of emotion, and the storylines are going to surprise people.”

Make sure you tune in for this special pre-season episode on Sept. 18 — and don’t miss the season three premiere on Sept. 25 on NBC.
