Kate: "What do you know about the other universe, those other doctors"
DW: "Have you ever been tuning a radio in and hearing a station you've never come across before and no matter how much you turn the dial you can't get it back? Well it was like that. For a few seconds I could hear them and they could hear me"
Kate: "What did you hear?'
DW: "Something terrifying, something beyond anything I could understand. That universe was howling in pain, burning in a sea of torment and I'm to blame...well they're to blame."
Kate: "Doctor, you...they...you're a force for good"
DW: "Good can create evil, just as evil can create good. Those Doctors Kate were trying to find some kind of balance, some kind of healing, to put right what they had done wrong, not deliberately, not purposefully but something they had done"
Kate: "Ok, so they made a mistake, but we all make mistakes. But they happened in a different universe, a different reality. You shouldn't feel guilty for what they did"
DW: "It's not guilt. I don't feel that"
Kate: "Then what do you feel?"
DW: "I don't know Kate, I just don't know...and that scares me"
