Not only am I manly and rugged, but I also have mad browsing skills.

Dan

Blair: Once [Chuck] sold me for a hotel.
Chuck: She knows, we have no secrets.
Blair: Blackmailers must be weeping all over town.

[to Blair] I know everything about you, which is why I know that your visit probably has more to do with a scheme than a scone.

Chuck

Old Chuck, Bad Chuck, New Chuck, Good Chuck.

[to Vanessa] I'm sorry, mom, I didn't realize when we moved in you'd be laundry monitor.

Dan

Serena: It was just so easy in Paris.
Blair: You were just so easy in Paris.

Do you remember when Chuck gave his heart to his mother? That was the beginning of the end. For all of us.

Blair

Blair: How could I still love you after what you did?
Chuck: So you did it just to hurt me. Eva made me into someone I was proud to be. You just brought back my worst self. This means war, Blair. Me versus you. No limits.

Chuck: Why did you drive the person I care most about out of town?
Blair: Eva left? Chuck I never meant to—
Chuck: Make her leave me? Of course you did. I need to know why. Is it possible you still love me?

I know what you did Blair. It's despicable even for you. Do you hate me so much you can't stand to see me happy?

Chuck

Serena: I guess it's for the best. If I end up with Dan, a part of me will always love Nate. If I end up with Nate, a part of me will always love Dan, so I don't know. I guess I just need to find someone who gives me what I get from both of them.
Blair: That's a mature decision. Not sure I've made many of my own for awhile.

[to Serena] No Dan? In that dress. I'm shocked.

Blair

Dorota: Sorry, Miss Blair. No papers today. I think maybe 8H steal them again.
Blair: Dorota. We both know it was you, not Susan Lucci, who took my papers. But there's no point. It's all over the Internet.
