Zeus was truly exasperated with Odin, 'disappointed that the iron doesn't turn into steel'. He never expected that Odin could actually get involved with Loki, that God of Mischief, and even join forces with other Eastern demon clans to wreak havoc everywhere.
These days, Zeus has been intensifying his efforts to gather information about the Nordic Pantheon, and gradually, Zeus has acquired quite a bit of dirt on Odin.
However, when Zeus was bombarded with these incoming reports, he wasn't in a good place at all.
Zeus had been looking for Odin precisely in the hopes that someone wouldn't continue to add to the chaos.
The reason for saving Zhe Yan today was that Zeus, Hades, and Poseidon happened to get the news that Odin would probably head south.
They were also taking a chance to see if they could have a... rendezvous with Odin, and now it seems like their luck wasn't too bad.
