Zach hadn't been sure when exactly Romilda would come over for lunch, and he didn't want to be in the middle of things when it did, so he had taken to reading. There was always plenty to read, and he was getting a strong background in a hell of a lot more theory. He wasn't thinking about his problems just yet. No, he liked to learn - then let it come naturally. But for that, he had to know more theory, which was really interesting actually, even if it took him a while to actually make sense of it. The stuff was complicated.
He bolted up at the sound at the door. "I've got it!" Zach called out, moving toward the door immediately anyway. He hadn't really mentioned the lunch to Gilbert, as he wasn't sure what to say. But he opened the door and was quite glad to see Romilda on the other side. "Come in," he greeted her, "I'll introduce you."
