Spoilers ahead from the "Game of Thrones" Season 7 finale.

How do you answer these charges ... Lord Baelish?

Sansa and Arya Stark had a tense reunion in "Game of Thrones" Season 7, but that Episode 7 finale scene with Littlefinger made it all worth it. Fans cheered on Twitter, with several reactions like this:

But the plot twist was less fun for Aidan Gillen, since he has to say goodbye to "Game of Thrones" before the final Season 8.

Gillen talked to Entertainment Weekly about how it felt to see Littlefinger killed off.

"You're left a little bereft — for your character and for your experience. It also immediately makes you quantify the hugeness of what that experience has been over the last seven years, which has been massive."

Gillen also talked a bit about that final death scene -- which turned into a surprise trial of Littlefinger, judged by Sansa Stark -- and the emotions it brought out of his character:

"I don't want to say too much about that. I don't want to lay my cards on the table. I want to preserve that. There were more feelings for Sansa than I've let on the in the past. It becomes obvious. It's an emotional farewell. And it's a humiliating position to be in. He's back in the sort of humiliating position that has been a driver for him: The rejection of Catelyn Stark, the humiliation by [Ned Stark's older brother] Brandon Stark — back when he cut him from navel to collarbone and didn't kill him [after their duel over Catelyn in their youth]. He's put back in that position again."

But Gillen said Littlefinger knew his plan to split the Stark sisters could "backfire," and it was so satisfying for viewers to hear Sansa use Littlefinger's own words against him in the end.

The best part was that it was a team effort by all three Starks -- Sansa, Arya, and Bran.

Yes, thank you for all your many lessons, Lord Baelish. We will never forget them.

"Game of Thrones" Season 8 starts filming in October for premiere in either 2018 or 2019.
