How do Du feel about the 12(13th) Doctor having a darker personality than some of the past Doctors we've seen before?

I don't mind. It could be a welcome change.

It could be cool a good change because when Du looked at it 9 had a serious nature to him 10 was half serious half funny and 11 was just like Paradox for every on!

I don't think Twelve will be any 'darker' than Nine, really. I'm excited for it because it'll be refreshing and different, at least.

I think it will be really cool to have a darker, possibly Mehr closed of Doctor.
