Lily was finally getting used to being back at Hogwarts. She spent a good deal of time wandering around, making a mental map of where things were. Having gotten caught up with the majority of people who she knew previously, and gotten to know her grandchildren a little, there was still the matter of checking on the person who had gotten her memories when she first arrived. Lily knew from the information Harry shared, that it was Regulus Black - brother of Sirius - who spent time walking in her shoes. And while she didn't think that there was anything in her past that might have scandalized the man, she still wanted to make sure he was alright.
She had to ask around in order to find him. Once she had, though, she genuinely wasn't certain on how to approach him other than by being up front with him. "Ah, no, I'm not lost," she laughed softly. She took a moment to consider her answer, aware that he most likely didn't have a positive opinion of her both due to the company she kept and her proximity to his brother. "I'm actually here to speak to you, Regulus. I'm to understand that you experienced my memories, and I wanted to make sure that you're not scarred for life."
