Oh, this is brilliant! You've covered things that hadn't occurred to me and yes, I think maybe the relationship is more sibling to sibling than parent to child (which is a lot more confortable, come to think of it, given the fact that I think Gwen does have a more carnal agenda than Jack). Thank you! Would it be all right, some time over the weekend, if I link through to this so people can see another viewpoint that tallies with mine?
