VIDEO: WestAllen Scenes Dominate New 'Flash' Trailer - Watch!

There are so many good WestAllen scenes in this new trailer for The Flash!

The little sneak peeks are really good, but also really heartbreaking because Barry (Grant Gustin), has just told Iris (Candice Patton), he watched her get murdered in the future by Savitar.

“Obviously Barry loves Iris more than anything,” co-showrunner Aaron Helbing shares, “and now that he has gotten a glimpse of the future, the thrust of the back half of the season is Barry trying to do whatever it takes to save her.”

Iris must be saved!

The Flash returns on January 24th on the CW.
