"It's never, ever closed off. It's all about 'Do you have a story that's worth it?'" Moffat told Zap2it this week in a new interview. "Unless you've got a story that is absolutely informed and invigorated by their presence, just bringing a character back in an ordinary story won't do."

According to Radio Times, he added: "Both River Song and Jack Harkness are massive characters in 'Doctor Who' mythology. Their returns would have to be seismic, not routine."

Fans of the series know that these storylines could easily come back, especially with the "time can be rewritten" motto that Moffat's Doctor always says. So will it happen?

"Sometimes you have to know when a story's over, you do," the head writer explained, making us a little less certain of these returns. "One of the things you always want to say is 'leave them wanting more.'"
