"Truth takes time"
"I've given you a gift... and all you get from me... is one."
"Whatever happens, there's something I need you to know... Sydney I love you"
"You may need to think of yourself as an honorable husband, a father figure. But I don't. I will never see that man in you."
"Never talk to me about your love for Sydney again."
From Counteragent when Vaughn visits Irina in her cell after he is cured.
IRINA: The problem, Mr. Vaughn, is that to the one person who matters, you haven't said anything.
VAUGHN: Listen, this may not mean anything to you. This may not be something you can understand or appreciate, but we have rules. Very clear and important rules that govern the relationship between a handler and his asset.
IRINA: And between a man and a woman?
Ah I loved that part. Its what made Vaughn finnally admit to himself how he felt about Syd.
