Lucifer smiles a little and nods. It is definitely a topic that Levi really couldn't do anything for and probably shouldn't be involved in. He's appreciative of the show of comfort though. He was sure the other angel would come around at some point. He was just impatient with the situation because it was painful and riled up his anger sometimes, though not at Balthazar. The anger had a vague 'whomever caused this needs beaten' feel and it was that lack of target that made it worse.

"Phenex will not allow you to do anything harmful. Though fallen, some of us still serve as guardian angels. Phenex is among those who have chosen that path."

"When the time comes I will summon them, provided Balthazar has no qualms about a strange angel being here with you." Lucifer remembered Balthazar being uncomfortable with Azazael just showing up and didn't want that to happen again. It was courtesy and respect for his lover's domain.
