Throughout Season 6 of The Flash, Barry Allen has grappled with his long-predicted death after learning that the coming "Crisis" had been moved up by five years, and in a new promo, he is tempted to leave his destiny behind.

The CW has released a clip for the first half of Season 6's two-part midseason finale titled "The Last Temptation of Barry Allen, Part One." As the "Crisis" approaches, the season's overarching villain Bloodwork plays mind games with Barry, attempting to take him over at his weakest point by playing on his fears of his looming mortality. Meanwhile, Barry's long-dead mother Nora Allen arrives to comfort him to do what he does best: keep moving forward.
