(Spoiler alert) At the very end of Fringe season four, our favorite Observer September delivered grave, unexplained news to Walter Bishop: “they are coming” he whispered before the screen went black. Well fellow Fringe fans, a shiny poster surfaced today featuring that mysterious, tantalizing bit of dialogue, as well as three bald-headed sharp-dressed men carrying black briefcases. It confirms what we all expected: season five will shed major light on the Observer-ruled world we glimpsed in episode 19 “Letters of Transit.”

The poster you see above will be the one fans will takeaway from the final Fringe panel at Comic Con later this month. Newly lone showrunner J.H. Wyman spoke to EW about the affair. “The Comic Con panel is something I always look forward to, but this year it’s bittersweet,” he said. “I think we have lots of good stuff in store for them.” The panel will be held inside the massive Hall H on Sunday, July 15 at 10AM. Series stars Anna Torv, Josh Jackson, Lance Reddick, Blair Brown, Jasika Nicole, and John Noble will join Wyman on a panel that will serve as a Q&A for fans and also include “an exclusive video presentation.”

Fringe begins its fifth and final 13-episode season on September 28 on FOX. The season premiere is called “Transilience Thought Unifier Model-11.” Yeah.
