For 'no one in the family looking happy' I've seen a ton of pictures today full of smiling faces. At the ceremony, of course, you could see some effort to not be bubbling over, it is a serious sort of moment, but as soon as they were out on the balcony the couple, the sisters, the kids -everybody was all smiles that I saw.
As for what the "reality" is; the "reality" is that unless you know the couple very personally you have no idea if they have an motivations other than romance for getting married. Albert was under no pressure to and Charlene didn't have to say "oui". Given that, I tend to give people the benefit of the doubt, take them at the word and, dare I say it, just look at how they appear together and from where I sit they seem like two people who are great friends who decided to marry.
I will never understand the instant negativity some people feel towards others who never did them the slightest harm.
The people have long wanted to have a 'family' back in the palace and naturally want their Prince to be happy. If they are, I am.
Vive l'Prince! Vive l'Princesse!
