I realized when looking back at the rest of this storyline that I had never actually explained how Lionel followed Loretta to her class, so I tried to do so here. He doesn't know transportation magic, of course -- neither Loretta nor her roommates are stupid enough to offer to teach any magic to her brother -- and Loretta's transportation pendant can only work for the person who's wearing it. So Loretta invited Lionel over and asked Aylia to transport him after her, which Aylia didn't mind doing.
