Day 5 - Your Favourite Companion. It does have to be CJH because, well. Look at him.
Not just that though, its also the fact that hes a really interesting character in doctor who terms, he is not exactly an angel, yet he seems to have come far further than most other companions, from being a con-man that is.
He is also the centre piece of a kick ass sister show, which is in the running for my favourite piece of tv EVER.
And because John Barrowman is such an awesome and talented person.
As Al Murray said about JB in TORCHWOOD “i think your the best actor in the world, and do you know why? Its pointless irrelevant twaddle and you make it so believable!”
