Erich did not wait a single moment to explain things to Tia. Instead, she was forced to reconnect to his NeuroLink and spy upon his memories herself. She was shocked at what she found, and remained completely and utterly silent. Her plan was to allow Erich to deal with these matters himself. After all, she had far more important things to focus on herself.
As for Erich himself, he immediately took the first ship he could find to the world of Svartalfheim. It was a world that Erich had never actually step foot on before. In fact, his only experience within Svartalfheim Territory within both of his attempts at life, was when he was held as a prisoner within an asteroid prison colony.
