Houten says it would be hard to find a role as interesting as the one she has played on the show, which just finished its seventh season run.
"I'm thinking, 'Ah, what a shame that it's going to end and I'm really not going to see a lot of people anymore', and I'm also sad that I'm not going to travel to Belfast. I'm going to have to look for another job that's equally interesting, which is going to be really difficult, because roles like that don't come along very often," Houten said in a release.
"... I've had loads of fun as well, even on really tough days like in the cave giving birth to the shadow baby; I mean there was Liam (Cunningham) there making jokes while the prosthetic team were blowing air up in my prosthetic belly, and it was funny as well. I'll miss it. But we still have one more season to go so it's not over yet."
