John Barrowman has teased that he’s returning to Cardiff for a secret project soon. Could it be a return to Doctor Who?
After he brought back Alex Kingston’s River Song for last year’s Doctor Who Christmas special, it’s starting to look like Steven Moffat may repeat the trick this year by bringing back another long-time absentee from the supporting cast for a festive reprive.
John Barrowman has teased that he has work in Cardiff in the near future, which has led the internet to suggest that he could be appearing in the 2016 Doctor Who Christmas special. Or maybe even the spin-off series, Class.

For the record, all Barrowman said – while promoting his new book in a Welsh Waterstones – was that “I will be back in Cardiff in about a week and a half… but I’m not telling you what for!”
That’s enough to get a rumour started, since the Welsh capital is synonymous with the production of Doctor Who at this stage. Perhaps it’s a bit soon to get excited, but the idea of Captain Jack Harkness bantering with Peter Capaldi’s Doctor is a tantalising proposition, isn’t it?

This chimes well with one particular statement from Capaldi: “I don’t know whether [the new companion] would be involved in the Christmas special, because it’s so specific, the story we’re doing with the companion.”
To kill a bit of time before Pearl Mackie’s Bill shows up then, Mr Barrowman may just get his chance to return to the Whoniverse.

Of course, we’ll let you know as we hear any more about this rumour.
