Gabriel is ready to quip- she doesn't know what it's like to be Lucifer's bro, that at least Lucifer is bringing her things that she likes, but all of those thoughts come to a halt when she mentions her arm. In that moment, all of the little things that had been subtly bothering him about her mannerisms and attitude suddenly coalesce into an actuality. He realizes then that her arm looks completely different to his senses. Before, there was energy, and an interesting otherworldly aspect. Now, the physical object is there but not the energy.

He sets his elbows on the table and leans forward to look over her. He has missed so much that's going on with her, and it seems like she needs something from him that he doesn't know enough to give. He's very worried that way more is wrong than she's even hinting at and suddenly, selfishly, wonders why she hadn't come to him with any of this earlier.

He pauses for a moment before speaking. "Iman," His tone is soft and lacking his earlier playfulness. He's attempting to sound caring, but it comes off as vaguely threatening because he feels hurt about not being included before now. "What happened to your arm?"
