First off, I have to say THANK YOU for not liking Clare and K.C. together....I sort of hate their characters in general but whatever.
Here are some sites that should help you out:
I love, love, love the show but season 1, 2, and 8 (maybe even 7) aren't necessarily worth watching. But you should at least check out seasons 3-6 they are really good.
The best episodes are probably:
-Rock This Town (season 6, episode 11) [episode topic: bullying/death]
-The Bitterest Pill (season 6, episode 12) [death]
-Time Stands Still part 1 & 2 (season 4, episodes 7-8) [bullying/school shooting]
-Back In Black (season 4, episode 9) [aftermath of school shooting]
-Secret part 1 & 2 (season 4, episodes 14-15) [oral sex/gonorrhea]
-Accidents Will Happen part 1 & 2 (season 3, episodes 14-15) [teen pregnancy/abortion]
-Our Lips Are Sealed part 1 & 2 (season 5, episode 15-16) [eating disorders]
-Venus part 1 & 2 (season 5, episode 1-2) [i dont really know what to call the topic for this one, its mostly about Manny and how she wants to be an actress but her dad wont let her and she gets drunk and Peter video tapes her topless and sends it around school and she gets kicked out of her house]
