"He WAS dead!" he snaps at her, then quickly backs down. "He was. He really and truly was. But...he's back. I don't know how, I really don't. And I think he was pulled here. We think somethings pulling people in, here. More than just normal Rift activity. It's...a theory in progress." He's pacing before her as he continues. "I didn't tell you because...because I didn't want it to be true. I thought...I don't know what I thought. That if I didn't say anything, it wasn't real, never happened, no Master in Cardiff, on we go happily unconcerned. But it was real, and I can't pretend it's not," he stops pacing, turning back to face her, "and I was so wrong not to tell you right away. Please forgive me, Rose. Forgive me, and help us?"
