How Long?

"How long have you known about your brother?" Wally asked Lylah. They were back in his office at the Academy. It was a homely looking space with three out of the four walls of his study being made of bookshelves that were filled completely with various tomes and recovered notebooks.

A fireplace sat in the middle of one of the walls and was lit, giving off a comfortable warmth and gentle glow to the room. He was quite proud of his little study that he had created using the space the Academy had given him. It was one of his favorite places whenever he was not out and about collecting notes and performing research.
