Alias, Season 3

Jack:
I didn't bring this up to start a petty fight. The fact is, you and I have something in common. We both suffered through the death of the woman we loved only to discover that she was still alive. I know, it's hard. But this isn't about you. And I will not allow my daughter to become your mistress.

Vaughn:
If that's where you think my concern for Sydney is headed, then you are even more cynical than I thought.

...

Jack:
If lightning strikes, Mr. Vaughn, and you and I get to walk free again, if you care about my daughter as you claim to, then push her away. Be cruel if you have to. Make her despise you because your kindness tortures her. I can see it, what it does to her. And I won't have it.
