I've been thinking about this situation from the point of view of astrology, since mum's been really upset and looking towards such things for some comfort. Disclaimer though - I enjoy reading about it and trying to figure things out sometimes, but have no expertise in these matters and don't even find all the online calculators etc to be very accurate.
Still working on my marketing materials right now so will be back with a detailed explanation later. Just leaving you all with the thought that as per astrology, things are going to get much better for Catherine, and therefore for William too, because a couple's destinies become entwined when they become a couple, and especially when they get married/enter into a commitment.
Also leaving you with this. Someone has to take the rulebook of titles to Google's head
