Yeh. Though the timeline of events we were given was fuzzy, it sounds like she let them summon Zodiark and then started lobbying her point. Zodiark was necessary for her plan too, after all. I always really did hate her logic of why she never told the Convocation what was up. She knew as much as Hermes what was happening. Hermes only knew more about Dynamis because no one else really cared. If she had gone up to the Convocation and told them what was up, perhaps they could have used that information to actually find a solution to the problem rather than just the stop gap they came up with. If they put their best minds on studying Dynamis, they prolly could have made quite a bit of progress.

Sadly we will never know.
