After Beta Milo from the Silverfur pack came to ask Cornelia to dance (and she rejected him), James' mood became unstable as he was fighting to control his wolf that craved violence.
James was gripping Cornelia's waist to the point of hurting, and she saw that he was on the verge of snapping.
At first, Cornelia wanted to scold him and tell him to stop being unreasonable, but a moment later, she realized that James grew up in a hostile environment that taught him people were sinister and always plotting something. In all that mess, she was his happy place, and he couldn't bear the possibility of losing her, even if it was only in his head.
How can she scold him for that?
Cornelia wanted to comfort him; to assure him that things will be alright and that no one can take her away, but how can she do that with all the audience? They needed to leave this party and find privacy.
"My leg is aching. Can you help me to my room?"
