Lucifer would look back at his daughter's friend. The person was sat on their own,injury over their chest from the battle with adam, how dare adam touch his daughter or her friends

Lucifer mumbled to himself "angelic weapons leave near premenant marks... Ah, there we go" he would grab a few golden bandages, infused with angel magic of course

he would walk over to them and begin to bandage up their wounds. His touch was gentle and caring too as he didn't want to cause further injury.
