Season 3 He never said to her that he doesn't love Sydney.

This was an except from their conversation.

Lauren: You still love her?
Vaughn: Damn it thats not what this is about. She is not my wife!

He changed the subject and never said no. Lol. Hahaha Lauren!

 

[Sydney CIA]

Yep. Noticed that too. Sure Lauren is his wife but there would be a big diffrence with this conversation:

Lauren: You still love her?
Vaughn: Sydney was my girlfriend and I loved her. You are my wife and I love you now.

instead of:

Lauren: You still love her?
Vaughn: Damn it thats not what this is about. She is not my wife!

I think there's a reason for him not saying what I just wrote. I think he still loves Syd.
