I'm having a hard time understanding why people think Venat telling the Convocation about Meteion and Hermes was a good idea, especially when Hermes now sits on the Convocation as Fandaniel. Hermes already showed his true intentions. And I doubt few would believe Venat's story. Emet-Selch didn't believe it even after he saw everything.

Hermes would actively work against her if she told him everything and would be smart enough to manipulate the Convocation against her. Not saying what she ultimately did was the perfect solution. Far from it. I'm just saying telling everyone would have been infinitely worse.
