I like how in this episode Brenda and Andrea start to build a friendship. Andrea has doubts about how serious Brenda is about joining "Rap Line" but in the end helps her save Bonnie. When Brenda was trying to tell Andrea what had happened the night before and Andrea wouldn't listen to her and simply jumped to the conclusion that she wouldn't be returning I wanted to slap her (Andrea that is). It was one of the reasons I didn't like Andrea early on in the series - she always had to be right and never gave anyone the benefit of the doubt - but towards the end of the eppy you can see that Andrea was starting to like Brenda and starting to trust her -- definitely character development
The one thing that I didn't like about Season 1 was how at the end of each eppy it was the end of the story - it was never revisited. It wasn't until the end of season one that they actually started to build and create actual storylines.
