When asked by host Stephen Colbert whether she had told anyone the long-anticipated ending, the Daenerys Targaryen actress said, “I’ve got to be honest, I did… I wasn’t supposed to, I told my mum.” Clarke added, “The good thing about telling my mom was that she’s a vault. Because she’s [already] forgotten it.”
Clarke learned her mother had already forgotten the details when she offhandedly mentioned to her mom that she already knew what happened — and her mom didn’t recall. “I’m kind of jealous of your mom,” Colbert replied; he said he wanted the ending told to him time and again.
“If she falls asleep on a plane, I’m quite worried she’s going to say it [talking in her sleep] and not know it happened,” Clarke joked.
In all seriousness, the actress said that when she finished reading the script for the final season, she said she started crying. “I went for a very long walk… I couldn’t quite handle that. It should have been raining, it was that kind of a moment,” she said. Clarke claimed she ended up walking around London for over two hours to process the script.
