Stiles actually glared at Alison because her question him along with Eterna was not helping the situation at all. Stiles felt vulnerable and angry, only able to tell the truth. He could feel the pressure built and he knew if he didn't start talking it would only increase.
"Yes! Yes, I want to stay with the bastard," Stiles said in anger before he was forced to answer Eterna's question. "I rebel because I do want my freedom but I also like him and I want to be with him. He makes me feel like I belong." Stiles seemed to unable to stop talking. "That I finally have a damn home. And do you really think I want to admit my feelings or desire for him? He is the one that branded me! He bought me and branded me and I should hate. Now stop asking me questions!"
