"Got that right, about the keys and all," Greg said partially under his breath, and then he looked at Zacharias as he continued to pet Theo like a well-loved dog. He did not try to lift him up as Theo had this habit of finding his way to the floor. Instead he offered an explanation of a sort, "Sometimes I wonder how he can keep things stored in his mind in such a way as it all comes out, sort of reality tangled with fiction. I didn't think he even knew," Greg said as he made as oddly approving face at Theo, "Snape is in charge and I got in a bit of trouble for using one, a key that is. Wanted Theo to try out the Prefect's bathroom. It was well worth it, but I'm not gonna try it again, I'll tell you," and Greg moved his hand to Theo's neck and shoulders, rubbing them with affection.
"I'll speak with him, Zacharias. It can't hurt to speak with him about it. And Theo you needn't worry about Professor Snape. He's already said that all I have to do is ask him when you want to go and he said we could visit the Astronomy Tower. And the Library as well. Please don't worry, honey," he said again in an effort to reassure the other man.
