One thing occurred to me watching the clips of Rawat with his father. I'm sure as in any family there is as much film of Hans with his other children as with Prem, but their absence from this film reinforces the belief that Hans had a special regard for his youngest.

It also avoids people asking questions about what happened to the brothers ( and mother ) who "disappeared"  ...oh..and the other brother who can be a bit of an embarrassment , apparently !
