Mykel and Amaryllis listened to the things that Sasha did before she came to see Mykel. They both had no idea that she sold The Lord's Disciples to Lucifer, and the fact that she worked for Lucifer was what angered Uriel. Mykel was surprised, the timid Sasha could do something like that, and he found it interesting.
They listened to every sin that Sasha had done after she got resurrected and chosen as one of The Lord's Disciples. They got a lot of information, including what kind of power Uriel possessed by watching her punish Sasha.
