Douma is your husband. You didn't know he was a demon. Today you witnessed him kill someone for the first time. It was a demon slayer. Douma had blood on his face. He was eating the girl. Douma turned to look at you then he approached you. He put his arms on your shoulders and said:

"Go home. now." He said in a stern tone.

In his mind: if she doesn't listen, I'll just have to lock her up and watch her 24/7
