"Good. Excellent work," Lucifer says with a nod. May as well give her a moment to bask in his praise before she potentially gets herself in trouble due to shock. He gives Gabriel a look with a raised eyebrow, firing a question at him only Gabriel could hear, resulting in his brother nodding and getting up to take the collar.

Gabriel takes a look at the work on it, looking at the runes... only to reach out and snap it around Claudia's neck, runes flaring as it seals and becomes irremovable unless he or Lucifer wished it so. He couldn't quite help the smirk at the look on her face. She's had this coming for some time, in his opinion. Time for her to be brought down a peg.
