[spoiler]Today's quote:
Ep #1186 (1841PT) - Catherine: 'He belongs to the past, and I MUST live my life by what is to be-- not by what has been.'
From "#1185/1186: Robservations 11/26/03: Deliberations Begin"
Daphne gasps as she sees her double join Catherine. I thought you were going to wait downstairs, says Catherine. I cannot tell a lie, confesses Daphne--I followed you up here and waited in the corridor. And listened? demands Catherine. Daphne nods. That's unforgivable, teases Catherine. I know, says Daphne, but you'll forgive me because you would have done the same thing yourself. If I couldn't control my curiosity, perhaps I would have, admits Catherine, smiling. I want to know why you didn't give Morgan an answer just now, says Daphne. You heard what I said, Catherine reminds her. I know, says Daphne, but I didn't believe your reason--Catherine, you're my sister and I love you, and I have to be honest with you, especially when you aren't being honest with yourself--you asked for more time because you're not sure of your love for Morgan. But you heard me tell him...begins Catherine. I know what I heard, says Daphne--and I also know your entire life, you've only loved one man. Catherine turns away--he's been gone five years, she says. I know, says Daphne, but there are rumors he's coming back! I don't want to talk about it, says Catherine. It's something you can't avoid, says Daphne--even when you were children, everyone knew how you felt about each other. When he left Collinwood, he left my life, insists Catherine. No, says Daphne, he'll never leave your life--and you'll never leave his. He belongs to the past, says Catherine, and I must lead my life by what is to be--not by what has been. He would be the last person in the world to accept that, says Daphne. We're discussing my life, not his, Catherine reminds her sister, and I will decide what is to be, not anyone else.

The Robservations references the quote perfectly...
And the reason the scene doesn't give any indication as to who the man is that PT's Catherine and Daphne are talking about is because theirs is part of the very first 1841PT scene. Obviously the writers wanted to leave the audience wondering so as to attract them to the upcoming storyline...
