Ianto is top - 'We could feed the world' still makes me chuckle. He was underused last series and I am glad he's come out of the shadows.
I do have a soft spot for jack largely because I love John Barrowman and he can do no wrong in my eyes - I even bought his album! Captain John was cool too, hope to see plenty more.
I like Owen enough although he annoys me a bit. Tosh I have no strong feelings for one way or another. Gwen is a pain, she has her moments but she gets on my nerves.
I actually really like Rhys now that he seems to be more involved.
