I am aware of all the potential creepiness and fakeness concerning this couple but I have to say they could also simply be a couple who didn't feel like kissing with a lot of people watching.
The same could be said for W&K, with their reluctance to show overt affection in public, but their abbrievated balcony kiss was
far more WAS genuine, compared to the farce we witnessed this weekend. If what half of what's posted in the "charlene's tried to run 3 times" thread is true, then it explains everything. Lord, have mercy.
Back on topic:
One of my favorite movies is Grace's last picture, High Society (a screenshot of which was posted above), made the year she married Rainier. I think that theirs was also a business arrangement in many ways, but certainly Rainier treated Grace better than Albie will ever treat poor Charlene.
