How else will this be solved, other than revealing Osiris as the FREAK he is? He would have to be brought to the court thing just like Set is doing rn and for that he would have to have it all revealed.
Revealing the rape would the quickest way for Seth to prove the mitigating circumstance that he needs to prove in be able to save himself from getting his soul destroyed, as it proves why it's plausible why Seth would have been so desperately scared of Osiris that he'd even resort to commiting the very crime he might get destroyed for (which is the crushing of human souls just to create the very only weapon that might have worked against an undead like Osiris). To prove why he was so desperate to protect himself from the dead Osiris, enough to commit such a serious crime just to create that one weapon, Seth would have to reveal the rape in to show the real extent of Osiris' harassment and obsession with him, which would in order prove why he had a legitimate reason for becoming desperate and thinking that an already dead Osiris would keep being such a serious threat to him, even from the afterlife...
Hot take but I dont really care that theyre revealing the rape in front of everyone. All the gods are technically related, they revealed that one girls infidelity and everyone knew about her being “locked” in prison, etc. Basically everyone knows everyone elses business anyways and it feels like these Gods function different from humans (since brothers and sisters are married together and Horus is Sets nephew or whateva)
