Dilan didn't spend too much time with the six Lesser Gods. He explained a few things, received their contacts and he left them behind afterward.
They were still baffled and had various questions but Dilan was not concerned about that. It was more important to beat up a few more Lesser Gods and show them the truth.
The Oracle and the Universe might dislike that he was willing to show others his memories because they were related to the City of Trials, the prophecy, and Hoert.
However, who said that Dilan had to care about their opinion and worries?
Showing his memories to others was the easiest way to show that the Universe had a hard time to face and that he actually needed the help of the Lesser Gods. Every single being with a certain combat prowess would be of help, whether it was to fight against Veilures below the rank equivalent to Gods, defend the Chaos Obelisks, or simply not obstruct Dilan and his people.
