When I was filming, I was staying in my own flat, says Barrowman.
People were saying to me, Why are you here?

And Im like, Im renovating one of our properties.
They fell for it.
But the irony is, I reallydidrenovate a property.
I was like, Im going to do work on this!
So, I kind of killed two birds with one stone.
Ihadto tell somebody, but I knew they would keep a secret.
ENTERTAINMENT WEEKLY: My mother lives about 45 minutes outside Cardiff.
I have somebody come in.
I said, Well put him though!
I just jumped around screaming, This is brilliant news!
And I said Yes right away.
I love playing him, I love what he stands for, I love who he is.
His response was Bloody marvelous!
And if they need help he will come back to help them.
So, to deliver that message about the lone Cyberman for me was kind of cool.
Can you expand at all on that message?I cannot!
Because if I expanded on it then it would be a spoiler and I would get in serious trouble!
But to be honest with you, I dont really know that much on the lone Cyberman.
I was never involved in any of the Cybermen episodes.
Its an acknowledgment that it doesnt really matter to him.
Steven Moffat.There you go!
[Laughs] So, with Steven, it wasnt going to happen.
But with Chris, there was always that chance because Chris was also a showrunner forTorchwood.
So, hes got a love for Captain Jack and I was glad that he called.
Will you be making my sister happy?That I cannot tell you.
I dont think its going to happen this season.
Doctor Whoairs Sundays at 8 p.m. On Jan. 31, the data pipe will also host a Captain Jack marathon showcasing episodes featuring Barrowmans character.
