And, you know, everyone in the audience is excited for our next guests but no one is more excited than this laid right you have been waiting for this for a long time. That's right, 58 days. 582 days. She knows because Amy is a "Game of thrones" superfan and fans around the world can't wait for the return of these on screen sister who is literally just about everywhere. Please welcome Sophie turner and Maisie Williams. Hey. How are you doing? Great to see you. Nice to see you. How are you? Great. Thank you, thank you two for being here. I mean this is the most anticipated finale season of any series ever in the history of TV. I mean -- if that's very nice of you. Sophie, I know your fiance, Joe Jonas, is a huge fan of the show. Have you told him the ending? I have. Well, actually he was on set for most of it so he kind of figured it out then he had to sign an nda. So, wait, he had to sign an nda. He had to have like full photo approval on set. His camera was covered up. Is he good at keeping secrets. No, he's terrible but -- Ki give him a call a little later. He'll probably tell you everything. You know, the final season premieres on your birthday. It does. How are you going to celebrate. Tax day too, right? Yes. I'm going to watch it with my family, be back home with them. It's been 582 days, not like anyone has been counting since the end of season seven so tell us, how would you describe the ending? Is it what people have been waiting for because obviously the finale, no one knows how it will wrap up. Beyond the books. How would you describe it? How would I describe it? I think it's hard to know how people predict it because we have people on set who were predicting it before we got the final season. I don't know what people are expecting. I don't know that people -- I think some people will be satisfied and others not so much. Not so much. You two really are close. You two really are close. We're sisters. Being that you've been there over the course of ten years with the show did you take anything from the set to -- Steal anything, let's be honest. I -- You stole something, right? Over the -- no. Over the years I collected little things, Arya had a little coin that I took. And then in the final season I got like one of my jackets that she wore but it's like covered in mud and blood so -- very "Game of thrones." It's like still sweaty. I tock my corset which I'm never going to wear because I hate it. It's the only thing that stayed with plea throughout the whole show. Yeah. And I took a scroll that was in the last -- like one of the last episodes and a huge spoiler and carrying it around in my wallet. Wow. That's good to know. You mentioned you're best friends and sisters on the show as well. You have matching tattoos. We do. Yeah. Right here. Oh, no, the other side. So what is the tattoo represent? This is the date that we got cast so the 7th of August, 29, we do our dates backward. In the uk. But that's when we got cast, so 2019. It's nearly our ten years of friendship. It's beautiful. You were separated on the show obviously and then when you were reunited, what was that like? Well, I don't think anyone liked it other than us. Yeah, I think we just chatted a lot and laughed a lot. Kept saying, no one really was that happy that we were back together because we just ruined everything. I think it was a bit of a relief for like the crew, the show is like really sad for most of the time and like when arcs are getting into character people try to be respectful awe -- although I think we should have been taking it more seriously. After nine years you get a bit jaded. Like kids in school, you have to separate the bad kid. Yeah, exactly. We know, Sophie, your character on the show has had two marriages. Yes. Neither one of them have been great. No. Not great. I don't have a good track record. But in your real life -- You are survived them. In reel life you do because you're going to marry Joe Jonas, one of the nicest guys out He is. Congratulations to you. How excited are you about that? I mean, I just hope that it's -- I hope I survive this one, you know. I hope it's a nice wedding. You have to do better than the other two. Awaiting the rsvp. The weddings have not been so yours will be much, much more festive and a lot less floody. On our show tomorrow, Gwendolyn, what she we ask her. She has a lot of interesting nicknames for the different cast members. Do you want to share yours? Well, I don't know -- is there she doesn't have one for me but you. Lady sansa. She said, lady sansa, nice to see you. Kit is baby boy, I think is kit. He loves that. Liam is granddad. Yeah. And alfie is alien. Yeah, it's cute. It's very interesting. I love that. Shoes's like the momma bear. Yeah, she's the momma bear. People cannot wait and -- When he says people, he means I know where to find you, parked in front of your TV. I'm having a "Game of thrones" party. I like that. Happy birthday to you too. Waiting for my rsvp. The final season of "Game of thrones" premieres Sunday, April 14th on HBO.
