I think it's because seth himself dont want anyone else to know what really happen the night osiris rape him, he said that he doesn't want his wife to know that he have been rape and that his wife might not see him as a man anymore, at the previous chap, god of sun suggest that they should put seth's heart on the scale to know what really happen but seth panic and shouts that he'd rather die than to let it happen and to help him, huros makes seth pretends to be knocked out so that no one can interrogate him

You're right!!.. but the fact that Seth didn't wanted to know about what happened between orisis and him wasn't because his pride would be hurt in front of the Ennead and other gods... IT'S THAT HE WAS AFRAID HIS WIFE WOULDN'T SEE HIM AS A MAN ANYMORE..how depressing is that...not others but his goddamn wife...
WHY THE HELL AIN'T NOBADY TALKING ABOUT ORISIS MATTER HUH... THEY'RE NOW GIVING HIM PUNISHMENT FOR THOSE CHILDREN AND WOMEN ONLY..COME ON...DIG MORE WHY SETH KILLED ORISIS AND ISN'T THERE A PUNISHMENT FOR CHEATING SPOUSES??...UGHHH MY BLOOD IS BOILING
