I don't really know why I'm a Jack/Gwen shipper. It just sort of works for me. Personally, I do see the chemistry. It's been there right from the start. They like each other, care about each other and are attracted to each other.

I'm not saying they should get together right away. What I like is the possibility that they might, the chemistry, lingering looks, hints that there are feelings there. Like with the Doctor and Rose.

That probably wasn't much help. I just thought I'd put in my two pence worth.
