Sunday's episode saw van Houten's character check an item off her to-do list: bringing together Jon Snow (Kit Harington) and Daenerys Targaryen (Emilia Clarke). She only stuck around long enough to witness Jon's arrival, but before she left, she dropped a very interesting prophecy. Her parting words predicted not only her death but that of Lord Varys (Conleth Hill).
"I will return, dear Spider, one last time," she told him. "I have to die in this strange country. Just like you."
When asked about her prophecy in an interview with Elle magazine, van Houten confirmed that she does believe both characters will die before the hit HBO series ends. However, she expects their deaths will be very different.
Varys, the actress predicts, will fight to survive but eventually succumb.
"Some things, terrible things, have to happen in these last seasons!" she said. "It'll probably be one of those where he'll try run from it, but he'll get it in the end."
Melisandre, on the other hand, will be more open to death.
"I have a feeling that she's tired. She's old, man," van Houten told the magazine. "She knows what this world is about. That's what makes her powerful, but also more vulnerable in the end."
The actress suggests that her character is "afraid of dying before seeing for herself that everything ends all right" and will do her best to make sure it does -- "even if it means she has to sacrifice herself."
We all know that Melisandre's methods can be terrible (like, say, burning an innocent girl to death), but if van Houten is right, she will do some good in the end.
"Game of Thrones" Season 7 airs Sundays at 9 p.m. ET/PT on HBO.
