Unfortunately, it looked like Misella's struggles were futile at the moment. She couldn't resist or free herself. Even though Atlas wasn't Castiel, he was still in Castiel's body which he had gotten accustomed to.
Misella's struggle continued for over an hour before she seemingly started regaining her senses in the absence of the blood. Her body did get accustomed to the Blood she had already drank.
"I... You are right. I can't treat it like a delicacy. I don't know what happened to me..."
Misella came to her senses, realizing just how strange she had been behaving.
"Nothing happened to you. It's the initial Bloodlust. Since you tasted it for the first time, your body wanted more which wasn't needed," Atlas explained, freeing Misella's hands.
