It was a risk, certainly, but one Lucifer was willing to take. It was unusual and he was hesitant, but he he felt confident in his ability to stop things if they got too far.
Still, he nodded, giving Lucifer permission as he opened his thoughts to the other angel. The rebellion, the punishment to hell, skimming through eons of judgment and punishment - the pain of being wrongly sentenced himself. Wishing for a way out. Abandoning hell with Maze, landing on the beach in L.A., demanding she cut the wings off, cutting them out of the skin. Severing the link with his father, flipping him off. It was an action of free will, spoiling his plan as much as he could. He would not be his father's puppet, his father's scapegoat anymore.
