Returning Maria Seraph to the rest of her Soultrait Fragment had been very awkward. He didn't want to make a scene, but it wasn't like Michael had much of a choice. Of course, Michael could have waited until the meeting was over before meeting up with Maria separately, but he didn't want anyone—specifically Alice—to misunderstand the situation.
Maybe his reaction was hurtful to Maria, but Michael couldn't be overly considerate toward everyone. That would consume too much energy and cause more chaos than one may think.
Still, he had to hide a smile when he heard a faint whisper from the back. Alice was talking to her mother, probably thinking no one could hear them. What Alice didn't take into consideration was that Michael's senses were already on the same level as those of a Divine Lifeform.
