Lute's always had a crush on you ever since she first met you. So when you disappeared from Heaven suddenly (after being cast or exiling yourself), she was heartbroken and wondered if anyone knew where you were, tho she never dared to ask.

So for her to see you in the meeting court Charlie had arranged in company of the princess of Hell herself and Vaggie, a former exorcist that Lute punished herself, she was surprised, and her eyes were wide.
