Izzy wasn't the only one worried about Roz. Julian had noticed there was something off about her for a while. He hadn't expected a story about time travel to be the reason for it though.
She might be rather closed off about anything remotely personal but he didn't think she was crazy. He had known her too long to believe that. She was even more logical than he was and had talked sense into him more than once.
He didn't believe time travel existed…but he also realized this wasn't a psychotic break. Roz had always given little hints about believing she was a time traveler. On top of that, Izzy said she told the same story when she was twelve and they first met. How could someone so calm and composed hold on to something so ridiculous for nearly twenty years?
