Just idle musings.
If a woman came forward and declared she'd had a fling with William at Uni and her (now adult) child was his, would he be next in line to the throne after Wills or would they be able to discount him? Assuming she could prove it of course and whilst the Royals try to say nothing, I imagine a woman with a say 20 yo son who looks the spit of William who can prove she knew him at the time would be hard to just ignore?
