Project Blue Book podcast 2.10: Aidan Gillen on that season finale twist in 'Operation Mainbrace'

By Tara Bennett
Project Blue Book S2 Operation Mainbrace

We've made it to the end of Project Blue Book Season 2 with the season finale, "Operation Mainbrace," and the writers certainly left us with a huge cliffhanger to sweat over for the duration. 

Per the urging of Senator John F. Kennedy (Caspar Phillipson), Dr. J. Allen Hynek (Aidan Gillen) and Captain Michael Quinn (Michael Malarkey) head out to sea to investigate some very strange sightings. It's up to the pair to keep a twitchy Naval Admiral (Colm Feore) from starting a war against the Russians, as they try to determine if something under the ocean is alien, or something else. 

Meanwhile back at the base in Ohio, General Harding (Neal McDonough) and General Valentine (Michael Harney) summon Mimi Hynek (Laura Mennell) to give a deposition regarding her relationship with Susie Miller (Ksenia Solo). As it turns out, her lingering anger opens the door for quite the confrontation...

As if all of that wasn't enough, the episode ends with us all asking — what happened to Quinn?!

Project Blue Book Season 2 Operation Mainbrace

**SPOILER WARNING: There are spoilers for Project Blue Book's "Operation Mainbrace" episode below!**

For the Season 2 finale of the Project Blue Book: The Official Podcast, SYFY WIRE senior producer and host Tara Bennett brings it to a close with executive producer/creator David O'Leary, executive producer/showrunner Sean Jablonski, and actor Aidan Gillen to unpack everything that happens in "Operation Mainbrace." There's Mimi and Susie's emotionally fraught talk, and the troubles at sea for #HyneQuinn. And then, last but in no way least, is that major cliffhanger involving Quinn, featuring the return of a very familiar face who might give Hynek some answers.
