“I cant tell you how, but he will.

He will also be on the TARDIS, Thirteens TARDIS.

Cant tell you how he gets there, but he will be there.

Its going to be epic.

Its just an epic episode.

In nutshell, its f—ing epic.”

ENTERTAINMENT WEEKLY: What kind of reaction have you gotten since your return was announced?

JOHN BARROWMAN: Ive had an unbelievable reaction.

People have contacted me and said, “My feed is clogged with ‘Jack is back.'”

But theres also controversy.

Buts it’s something to look forward to.

Putting the spoiler aside, I want the show to do well.

I want the reaction to be good, because there’s a possibility that they could bring him back.

So, I apologize for the spoiler, but I kind of dont.

What else can you say abut the holiday special?

Theres a wonderful conversation between Yaz (Mandip Gill) and Jack.

So, the episode touches on current issues but in a way thats very entertaining.

He loves a sofa!

[Laughs]

Will we be seeing any of that between the Captain and the Doctor?

It would be out of line if I were to discuss Jacks exploits with anybody without his permission.

Lets just say, Jack is Jack and Chris Chibnall (Doctor Whoshowrunner) knows Jack really well.

So, yes, there will be some flirtation.

The two heats of the Doctor will be beating, I hope.

Chris Noth is also on the episode.

Did you and he discuss haircare at all?

He and I had a blast.

Everybody thinks of Chris as Mr Big.

He is f—ing nuts and I love him.

We are both off the wall.

This is something I can deal with.

But the haircare lets just say there was a lot of product.

I have my particular product I like to use and he has his particular product.

And the makeup trailer was always a barrel of laughs.

Darling, dont worry.

A little olive oil, rub it in, youll be fine.

And then you could squeeze it and cook with it later!

Will be seeing more of Captain Jack after this episode?

I cant answer that, because I dont know.

Ill make it work, Ill figure out a way.

It will always happen.

What was it like being back on the TARDIS?

I’ve been in a few incarnations of the TARDIS myself, with Nine, Ten, now Thirteen.

Although its different, it still stands for the same thing.

When I walked back into that TARDIS, it was the same thing.

I felt like I was coming home again.

It means so much to me and I know it means so much to the audience.

However you define yourself, the Doctor accepts you and doesnt care.

And, as a real person, thats how I feel when Im in the TARDIS.
