ANNIE: (still dangling below ledge) Hello up there! Remember me? I'm the one you used to care about a minute ago.
OLIVIA: The one we don't give a damn about now.

Gregory is impressed that Annie faked a suicide attempt to get him to admit he cares about her. (Aug. 27, 1998)
GREGORY: I just can't get over it--you did all this for me.
OLIVIA: She did it to get her stock back.
ANNIE: It worked, didn't it?
OLIVIA: I think I'm going to be sick.
Note: Gregory reneged on the bargain and did not return Annie's stock.

Aug. 27, 1998
OLIVIA: (about Annie) Gregory, you are the one who's being pulled in, and I can't believe you're falling for a slut like this. You never used to be this stupid.

Annie just learned that Gregory controls her Liberty Corp. stock. She runs off in tears, and Olivia follows to attack her at this low point. Finished, Olivia re-joins A.J. and Gregory. (Aug. 24, 1998)
GREGORY: What did you say to Annie?
OLIVIA: Oh, nothing... that she didn't deserve to hear.
GREGORY: What did you say to her?
OLIVIA: Don't worry, Gregory. I'm sure that you and Weeping Beauty will live happily ever after.
Annie runs past, still crying.
GREGORY: (following her) Annie! Annie!
OLIVIA: (to A.J.) Oh, I can't remember when I've had this much fun. I mean, seeing Annie's sham of a marriage to Gregory exposed for what it really is--that alone is worth the price of admission.

OLIVIA: I haven't murdered anyone yet, but I should. I should kill you.

Annie shows off her new necklace. (Oct. 26, 1998)

OLIVIA: And who are you going as, Annie? The town harlot?
Later:
OLIVIA: I had to insult you, Annie. Otherwise, they would all have thought something was wrong.

Olivia is blackmailing Annie. (October 1998)
OLIVIA: If you don't do EXACTLY as I have asked you to...
ANNIE: I know, [mimics Olivia's accent] "Wear the necklace to the party, make sure Cole sees it, and make sure Cole steals it."
OLIVIA: Exactly. And by the way, you should definitely keep the accent. It made you sound just a tad more intelligent.

Annie and Caitlin need money for the blackmailer. (Dec. 5, 1998)
ANNIE: We're going to figure out a way to get a million dollars.
CAITLIN: I could kill you and get the insurance money.
ANNIE: Oh, well, that's a great idea, coming from a girl who doesn't have a brain.

Olivia is surprised to see Annie alive, since everyone believed she had died weeks earlier. (April 28, 1997)
ANNIE: Yes, Olivia, IŽm alive! I bet you wished youŽd turned that crematorium oven on by yourself.

OLIVIA: It all started the day you were born with half a brain, and you attempted to use the half of the brain that you were born with to blackmail me! (imitates Amy's voice) Oh, I'll give Ms. Richards an alibi for the night that Francesca was shot and then I'll blackmail her into fixing me up with Sean! (normal voice) Well, Amy, you were so busy blackmailing me that you forgot to tell your even more stupid friend [Brad] to back up the phony alibi you were giving me!

At Bernie Nielsen's party. (fall 1998)
LEO: Gee, Dad, thanks for making me the token teenager.
OLIVIA: Oh, don't worry, Leo. You're far more interesting than anyone here who's old enough to drive.
