While The CW dropped a trailer for the two-part crossover episode earlier this week, today they uploaded an extended trailer that reveals some of Kendra/Hawkgirl's (Ciara Renee) back story with villain Vandal Savage (Casper Crump). According to Malcolm Merlyn (John Barrowman), Vandal Savage has been pursuing Kendra for centuries, dating back to the time of the pyramids in Egypt.
Newcomer Carter Hall/Hawkman (Falk Hentschel) also tells Kendra that while she may not remember her past with Savage now, she can expect her memories to start returning to her. This story will be explored more fully in the upcoming show "Legends of Tomorrow", but will be introduced in a major way during the crossover event.
Check out the extender trailer below:
