But I think since Victoria is married and will likely start having kids ASAP, I don't look for him to settle down with anyone for long time I don't think we have to worry about him marrying Sofia.
Do you mean, that he would worry for the dynasty otherwise?
I don´t see such worries with him.
And I wouldn´t be surprised, if things would go fast with "Princess Sofia" At least she is going with full speed and is reading UN children rights at the university and global law and is expanding a charity project in South Africa.
Might be though she is a bit too fast and crashing against a wall named Ma&Pa Bernadotte
