Mykel decided to leave the two of them and went back to Earth because he had been gone for a very long time. He wanted to see what everyone was doing, and he wanted to know the progress of everything.
"This is your first time coming to this world, so don't make a ruckus like your brother," Mykel said to Spenta who was clinging onto his right shoulder and looking at the city from Mykel's office.
"(Where's my brother, father?)" Spenta asked.
Mykel only knew that Spenta could talk when Loki told him, but Spenta could only speak to him telepathically. Loki believed that Spenta was still too young to be able to speak, and Mykel found out that Spenta was a shy type so he didn't like being in the center of attention.
