WHY aren't they having Thoth to question the mirror demon thing!?

Bcuz thoth maintains a strict "doesn involve in ppls business to avoid changing future events" as the god with future foresight he's n observer as he knows even slightest change here or there can cause ripple in flow of events. N whatever is unfolding rn is a very imp event that has to happen. Aha..

Also maybe seth doesnt like airing his dirty laundry infront of outsiders. Even at trial he didnt speak abt his rape cuz of his thin face n dignity. So cant imagine him opening up to thoth abt all this.
