(How can they fight like cats and dogs when they are mouse and bird? Also, Mort would win.)

The tension may be gone from Thanatos, but he is far from relaxed. He lets Mort handle the conversation. Or at least he did before it got turned back on him. Blood and darkness....

"I did not. My mother made Mort." And... Thanatos doesn't elaborate on that. He glances at Ryo. What does he want from this? They all know Ryo. They are all twins, but what does this accomplish? He can't get to know Endon and Orion in this short period of time, and they are unlikely to meet again in the future.

Is there some knowledge he is supposed to impart to them? Thanatos certainly can't give them any favor.
