Ianto's confused at first how Noah knows Torchwood, but then he remembers that Noah had read his dreams before. He must have gotten Torchwood from Ianto's mind as well.

"Torchwood is where I worked," he tells Noah. "We investigated strange occurrences, aliens, people who ended up in the wrong time, demons," he tries to explain, never quite sure how to put it. "But not murderers," he adds softly. "Not regular human murderers."

He takes a breath. "Sometimes I wonder if there's a way to see if it is in my memory," he tells Noah, his voice shaking a little. "But then I'm afraid I'll learn something I don't want to remember."
