Gareth about John
This is actually an interview to Gareth, there's no spoilers (though they do say what they mean when they mention the families), though there's one at the very end of the interview so if you don't want to know, don't read the very last part. I'm posting because he is asked about John twice. (don't know if there would be spoilers in the comments inside the link so watch it)

The first question is in reference of reports of John being upset about only having 5 episodes.
Can you give me an idea of exactly, is he very upset about this, or just kind of annoyed?
I'm not... I mean, he's never been serious about anything (laughs) I think he's just, he loves the show so much and put so much into it, I think he would have liked to do it a bit longer
Would it surprise you a lot if John Barrowman revealed he was actually a 51st century con man?
No, not really. I mean (laughs) he always looks in great condition and his hair's always perfect, in place, so it wouldn't surprise me at all if he said he was from the 51st century and he could live forever.
There you go.
