lol its a joke in the cultura language,it simply means he sees him like a children or a great friend and indeed he's been speaking highly of heritier for well over a decade he already said it about his vieux karmapa and jb for exemple
i knew people would notice that,cultura have a whole lot of expressions only a person around the group can really understand
for example faux mutu which for normal people means a bad person in cultura means a close friend,a buddy or to bebisa nanu which means lets spoil something,in the cultura language it means lets try our idea and see what we get from it
by the way about his skin,he is been developping along with another of his brothers some patches of a different complexion to his skin color dont think its vitiligo but they inherited it from their late dad and both started having it in their 50's
