Warning: Spoiler alert! Do not proceed if you have not watched Tuesday's episode of Prison Break.
Did we just find out Poseidon's identity?
At the end of Tuesday's episode of Prison Break, titled "The Prisoner's Dilemma," the mysterious figurehead -- only known as "a rogue CIA operative" -- was possibly revealed to be Sara's husband, Jacob Ness (Mark Feuerstein), as he was spotted by T-Bag (Robert Knepper) talking to two henchmen, A&W (Marina Benedict) and Van Gogh (Steve Mouzakis). But, is Jacob really Poseidon?
"There are definitely a number of more moves to that story," creator Paul T. Scheuring exclusively tells ET. "The idea is to say, 'Boy, that sure looks like it's Jacob. Jacob sure looks like [he's] Poseidon.' All roads point to him at that point, but like I said, that is not the final understanding of Poseidon or Jacob."
Though Scheuring was coy, he did note that the identity of Poseidon is "more complex" than anyone could have imagined. But for the time being, it does appear that Jacob may be working against Sara.
"He does not, in that moment, seem to be on the right side," he confirmed.
And don't expect T-Bag to be keeping his revelation from Sara (Sarah Wayne Callies), his new unlikely ally. "Oh yes, he's coming right back to her. He's going to tell her everything," Scheuring said.
With Sara armed with potentially damaging intel on her husband, their marriage will become strained -- and understandably so.
"At least with that information, in [the next] episode, she's going to realize she's sleeping with the enemy," Scheuring teased. "But is that the final twist or are there more twists in that storyline? Is it a misunderstanding?"
"There are more moves in that storyline subsequently," he continued, reiterating his prior comments, "but for now, at the end of the episode, [Jacob] sure looks a hell of a lot like Poseidon."
Poseidon, though, has a masterplan and it somehow involves Michael (Wentworth Miller), a point Scheuring emphasized: "On some level, the whole thing is a head game played by Poseidon on Michael and then Michael, in turn, has a head game to play on Poseidon, where down is up and everything you think you know is not true. We're hoping that we blow the audience's mind in the last episode."
Meanwhile, Michael, Whip (Augustus Prew) and Ja (Rick Yune) successfully break out of the Ogygia prison, and Michael is finally reunited with his brother, Lincoln (Dominic Purcell). But they're faced with a new challenge: How will they get out of Yemen alive when there's a bounty on their heads?
"While before they had people in the government in Yemen helping them, now that the government has fallen, all their resources in Yemen have fallen apart. All the official means of egress, in terms of the airport and what have you, are controlled by ISIS," Scheuring said.
"It's not as easy as getting on a jet and flying out of there. Now they have to figure out how to get out of the city and how to get out of the country without the airport and that takes them across the world, essentially. There are no short flights back to Ithaca, [New York,] to see Jacob and Sara," he added, teasing that they'll find themselves in "many more settings," such as desert and ocean.
That means Michael and Sara's anticipated meeting won't happen for at least another few weeks. "But it will be before the last episode," Scheuring promised. "We're not going to starve the fans until [the finale], I promise you that."
The episode also saw the death of Paul Kellerman (Paul Adelstein), a character who first appeared in the series debut in 2005, which begs the question: Are more deaths awaiting our Prison Break favorites before the nine episodes are over?
"There will be more deaths this season," Scheuring warned. "Unless you're killing people, there are no stakes."
Prison Break airs Tuesdays at 9 p.m. ET/PT on Fox.
