At that time, two people entered the Unity Inn. Lilly shows a Fake-Gemini Clone with her eyes. Her face still shows that something is not right, but it is not that important. She made her decision to help to authorities to ambush and set a trap to Fraus. This thing was all needed for Fraus to sign her death with his mind.
People should treat these kinds of things in the eyes of others as only to be expected.
Lilly is not a spy or something like that. She is just a run-of-the-mill city girl who works at an inn. Normally, she would be showing some sort of thing that she should not be showing.
But what can people expect when these kinds of matters arise? It is easy to see and understand.
Fraus can see everything through his eyes, and if he wants to do something, he can do it without too much difficulty.
It is not that he is planning to try with everything, but there is no need for him to not be prepared.
