Fans got to witness Gwendoline Christie's character Brienne serve up some long deserving justice in last Sunday night's season finale of 'Game of Thrones.'

It at least appears that Brienne kills Stannis Baratheon at the end, as the scene cuts away during the final blow.

Christie was available to speak on the dramatic scene with EW and where her character is right now.

Here's her response to the Stannis scene:

"This season we see Brienne start to activate different parts of herself that she hasn't had before. She starts to get a little bit more clever in the way she deals with people. The scene where they're in the inn with the innkeeper and she asks have you lived here long and asks, 'Do you know who lives in the castle?' She says, 'I swore an oath to Catelyn Stark.' And through that gains information from him. This isn't the Brienne in season 2, this is a person who's looking at life and seeing the best routes to achieve what she wants."

She also speaks on her character's feelings about leaving the watch for Sansa:

"Brienne is depressed about the situation she's in. She hasn't been able to achieve what she's wanted. Arya slipped through her fingers and she just went through the fight of her life. The notion of the oath comes up again and again and she remains resolute. A lot of her personal needs remain unacknowledged. She puts all of her life's focus on the greater good. What occurs is something very interesting. There's an exploration of this character as a person-she's dedicated to the greater good, not acknowledging her personal wants and needs in favor of something better than her. [Going after Stannis is] the one moment she responds to her emotional world and her feelings. She's overtaken by something that we haven't seen before. She chooses not to stand vigilant and to go and seek Stannis. In the script it says, 'a darkness comes over her,' in that way it does when you're hell-bent on something."

Christie finishes with saying that she in no way knows what is fated to happen with her character, however she is prepared for the worst.
