Flashpoint was big, but whatever challenge Barry Allen is about to face next is even bigger. Speaking to IGN, Andrew Kreisberg revealed that "The Present" -- the mid-season finale of "The Flash" -- will present a new puzzle piece to the Flashpoint mystery, and it may even be more significant than Barry's decision to change the past.

"The mid-season finale [airing Dec. 6] kind of creates a new problem for our heroes that they weren’t anticipating, something that they’ve never faced before,” Kreisberg explained. “It’s so big, we’re actually considering changing the saga sell from talking about Flashpoint to talking about that, because that’s really what’s driving the episodes for the rest of the season.”

“The message from the future relates to Flashpoint, but it also may relate to something else coming up,” he added.

Of course, we know several of the elements that are going to factor into the mid-season finale, thanks in part to a promo and some photos. For one, John Wesley Shipp's Jay Garrick will be back in action when Barry goes to visit him on Earth-3, and that's where Barry will encounter Mark Hamill's James Jesse. As we saw in "Killer Frost," Doctor Alchemy -- or Julian Albert, as we all know him -- is back in business. It also looks like Savitar will show up as well, and Jay will be able to see him (much to Barry's relief). Additionally, Caitlin is still struggling to repress her Killer Frost persona, and there's always danger of that rearing its ugly head again. Now, none of these elements could be involved in the big reveal Kreisberg mentions, but they're worth pointing out.

It's also worth noting the message from future Barry, which was revealed in The CW's four-show "Invasion!" crossover. The message — which was addressed to Rip Hunter — referenced Flashpoint, as older Barry explained that he had gone back and altered the past, thereby affecting the future. He warned of a coming war, though it was unclear if the fight he was referencing was with the Dominators, and told Rip not to trust him under any circumstances.

Starring Grant Gustin as the Scarlet Speedster, "The Flash" airs Tuesdays at 8 pm ET/PT on The CW. The series also stars Jesse L. Martin, Tom Cavanagh, Carlos Valdes, Candice Patton, Danielle Panabaker, Keiynan Lonsdale and more.
