Speaking to Glamour, Sam explained: “To be honest, I think there’s still stuff to be revealed [with Claire’s powers].
“I sort of secretly know what it is, but [it’ll be] revealed by Diana [Gabaldon, writer of the books] with these next few books and the next few seasons.”
However Sam went on to drop a huge hint about his character’s relationship, and it doesn’t sound good.
“For the time being,” Sam said. “Jamie has chosen to remain here on this planet with Claire and they need each other.”
