This starts right after Carrie tells Sami/Austin that she is pregnant (Lucas already knows because she already told him in private). We are in Lucas's living room.

Everyone stands in silence for a couple seconds as they all look at each other.

Carrie: Well lets not all jump for joy at once

Sami: Pregnant? Oh my god Carrie. Congratulations (after some hesitation she hugs her sister). Wow, you too Lucas.

Austin: A baby. Wow that was fast. (Austin looks shocked as all hell)

Lucas: Yea well it was unexpected, but we are both very happy. (He looks at Carrie with a big smile on his face) Wow! We are actually doing this. We are having a baby (and they kiss)

Sami looks up at Austin who is still in disbelief as a sudden feel of guilt comes across her.

Austin: Congratulations, I really meant it. I am happy for the both of you, if you are.

Lucas: Yea we are both really happy

As Lucas says this Carrie gives some half-ass smile

Sami: Well excuse me but Austin and I have to take care of some business-

Austin: Yea, we do. Umm, once again congrats on your baby. And...well...yea congratulations.

Austin and Sami both leave to go to her apartment

Austin: Thanks for saving me, I guess you could tell that I really didn't want to be in there.

Sami: Well, I didn't really pull us out of there for you. We need to talk and talk now Austin.

Austin: Is something wrong? Are you ok? Beside Lucas and Carrie.

Sami: Well if you should know this has nothing to do with Lucas and Carries instead it has everything to do with you. And to answer your question, no, and you are the problem.
