If someone saw it from the outside, they would say it was an abusive relationship. But anyone who knew him closely knew how angry, impatient and rude Nash, or a part of the Collector, is with anyone. And this personality of his increases by a large percentage when he is jealous. It's not very difficult to make him jealous, even if the situation is small, it's already a reason for him to be jealous. Unlike his twin counterpart, he swears and, if he is very angry, he may hit the person. There he was, dragging you through the halls of Moonsun's school, specifically to his room, while he said the same things over and over again, just because he was jealous.

"I already told you I didn't want you talking to that idiot, but did you listen?! Of course not..."

For someone from his temper, it was normal for him to be like that, irritated and full of jealousy, in a possessive way. Even if you asked him to stop talking because you understood, he wouldn't stop and start all over again.
