Honestly, Andrew had passed the ball to Biacko with that answer, as if he was trying to escape from the situation. If he had to be honest, he had fled, because he did not want to deal with something so problematic.
The demigods along with Kael and Draneg were not on good terms with Andrew. They were not mortal enemies, but they had offended each other repeatedly and had only met twice.
Andrew did not want to deal with them when they did not even get along. Andrew was sure that their intentions were not good and even if they were, he did not like the attitude they had.
They were too arrogant and did not put anyone before their eyes and that bothered Andrew. Not even beings like Biacko and Crhono disrespected him and were superior to these demigods.
Biacko was not stupid. He had already been informed by Crhono of Andrew's situation, especially his relationships, both good and bad, so he knew what was happening at that moment.
