Do you not think that Prince Carl Philip would look to his father as a mentor?
Hopefully not. Seriously. CG does not have many good father qualities IMO. If the kids get interviewed they talk about how lonely their childhood was and Victoria got anorexic. Plus: they totally missed preparing the spare and the spare spare for the "real world" and just realized a few years ago that it was time to take the titles of their grandchildren and expect them to work. Other royal houses were light years ahead of them (they should have talked to Bea).
It is a pity that CP never found a real meaning in professional life beyond car-racing and "designing". As Sophia has similar minded parents it is good they are having some mentors outside the royal family.
