He is a bad example
After the servant tells them that they have to hurry to the hall for dinner, Nell heads out of the room with Eli rushing behind her.
Eli realises that she is fuming. He can sense the anger radiating from her. Watching her from behind, he realises that he shouldn't have been picky. They are engaged, nearly married. Isn't this what he wanted? He also knows that she loves him. Then, why is he acting greedily? He should be satisfied with what they have. When the time comes, she will tell him.
"Wife, I change my mind." He fists his hands nervously, lowering his head a little while following her from behind. She is short, but she is intimidating enough. He regrets demanding a proper kiss. "I won't behave anymore. Let's go back to our room."
