I am excited for next week's ...

Question: I am excited for next week's 100th episode of One Tree Hill and I know deep down you are, too. Answer: I'm so excited that the second the screener arrived, I handed it off to my colleague Robyn Ross, who proceeded to jump up and down for 10 minutes straight before passing out. She eventually came to, watched the episode at her desk, and filed this spoiler-laced report:  • Haley and Nathan’s worst nightmare comes true when two people from their past return. • Karen reappears with a former series regular. • Lucas and Lindsey's wedding ends with **** *n* of **** ***ing "* **."• One of the four main girls tells Lucas she wants to have his baby — and it's not who you think.
