Lucas believed he saw more then an auction slave's duty when Nathan kissed Peyton, but confronted Nathan is convincingly indignant. Brooke and a test kit tell Lucas they're expecting a baby. Jake still refuses Nikki any part in Jenny's life. Nathan tells Haley he doesn't understand she won't share his bed but tattooed his jersey number on her backside. After 15 years Keith proposes to Karen, who 'isn't ready', and decides to leave. Dan tells Lucas not to let Brooke ruin his life as Karen did by having him; and bursts in at Nathan's to tell him the beach-house will be waiting 'when' he hits rock bottom. Written by KGF Vissers

Did You Know?


When Nicki is looking at Jake's photos on the fireplace mantel he has his back turned to it. If you look right behind him before the scene ends, you can glimpse a picture of Bryan Greenberg (Jake) with OTH creator Mark Schwahn. See more »


Brooke: I lied.
Lucas: What?
Brooke: I'm not pregnant.
Lucas: Wha - But I saw the test.
Brooke: I know. And when the doctor called, he said I wasn't pregnant. He said that can happen.
Lucas: Okay, no-no-no-no no. I-I-I was standing right there when he called.
Brooke: And you had just called me a slut.
Lucas: So you lied to me to punish me? How could you do that?
Brooke: How could you cheat on me with my best friend?
Lucas: Brooke, I never meant to hurt you.

I love you and it scares me a little bit, but there it is
15 February 2013 | by See all my reviews

OMG Brooke pregnant, and Lucas is perfect as always, doing what is the right thing to do.

The scene where Lucas told his mum that Brooke was pregnant was great. Very good emotion. I got some tears, you know the good kind you get when a show moves you.

I don't really get Karens rejection. She's just mean for stringing him along all these years. Surely she knew.

The writers are confusing me about Dans intentions. The keepsake of Lucas is in direct contrast to many other aspects of his character. I don't know if I should like or hate him, and I think I'm doing both at the same time. One odd thing that occurred to me is, how did Dan get copies of Lucas' school photos? They looked professional to me.
