Game of Thrones: Aidan Gillen Will Never Reveal Littlefinger's Final Words

SPOILER WARNING: The following contains spoilers from Game of Thrones' Season 7 finale. 

During the season finale of HBO's Game of Thrones, longtime strategist Lord Petyr 'Littlefinger' Baelish met his end, courtesy of Stark sisters Arya and Sansa. During his final moments, he began to speak, but only got so far as uttering a final "I..." before expiring. If you're wondering what his last words were going to be, actor Aiden Gillen says you'll have to look elsewhere, because he's never going to spill the beans.

"Actors have a responsibility to interpret a character and bring something of their own," Gillen told the LA Times in a post-finale interview. "They have a duty to protect the dignity and the mystery of the character, including not over-discussing details like that, after the fact. I think over-discussing things, particularly in a show that’s as over-discussed as Game of Thrones is diminishing. My job, as this character, will probably go on for a while avoiding questions like that."

The actor also added that he'll take that secret to his grave, much like his character. Despite Littlefinger's recent demise, a death the actor says he found "liberating," Gillen said he greatly enjoyed his time on Game of Thrones, saying tat early one he felt he "was going to be part of something quite remarkable...and it was."

Game of Thrones’ final season doesn’t yet have a release date, but the penultimate season is now available in full on HBO Go and HBO Now. Based on George R.R. Martin’s bestselling fantasy series A Song of Ice and Fire, the hit drama stars Peter Dinklage as Tyrion Lannister, Nikolaj Coster-Waldau as Jaime Lannister, Lena Headey as Cersei Lannister, Emilia Clarke as Daenerys Targaryen and Kit Harington as Jon Snow.
