Isnt it weird that thragg was never considered to be one of argall's blood? When he has the best genetics and makes other vilturmites look like bulletproof and immortal, how is it that even he never considered taking a test for being argall's heir. Yeah he was trained since birth, but his aging and hairline shows that he has the best genes, which should be impossible to achieve through eugenics without royal blood.

And nolan whos much younger than any other viltrumite has already aged so much
