"To be honest Sev, I don't know," Lily admitted. She had no idea what caused the Tesseract to do the things it did, or to choose the people it did to do it too. The question she couldn't help but wonder was whether or not this would be a permanent change, and if she ought to be inviting Severus back to live with her and James and Harry. On the bright side, she supposed, James was an adult and Severus hadn't met him yet on the train, so if it did come to that, then hopefully the two of them would get along better than they ever had in their home world.
"All right, let me go check it." Lily got up and left the tea on the nearby table and then headed into the bedroom. It was odd to be in Severus' bedroom without him -- not that it would have been less odd to be in it with him -- it just was all around odd, perhaps because with someone like Sev it felt even more intimate than it might have with others who held themselves less tightly. She stepped in, taking note of the photos of Severus at various points throughout his life, his mother, photos with her, photos with his classmates. She stopped over one that appeared that it must have been taken when he as teaching at Hogwarts, but he couldn't have been there very long because he looked almost as young as she remembered seeing him last -- nothing like he looked now, or how he had looked before he became eleven. She touched the frame gently and picked up his phone off the bedside table bringing it back into the room. The missed call from Harry was there, and the one from herself.
"All right, this is a phone, Sev, but it's not like the ones we have when we're kids. It's a lot more than that. It has a map, and you can send messages to people instantaneously, and you can send letters instantaneously. And probably it plays music, or mine does, but I don't know if you've got any on here. And you can access books, and the Internet, which -- more or less jut a giant network of connected pages..." she hesitated trying to decide if that was a good descriptor or not. "More or less."
