The writing on this episode was very, very strong IMO; and it needed to be to be an "event" episode that didn't jump the shark. I loved the way that it further muddied the waters between Dr. Brown and Dr. Abbott's ideologies; it's a dynamic that continues to grow with each episode. I like how their integrating Delia into more episodes, and what her experiences say about Dr. Brown himself. I also liked how they tied it all into the coming of age subtext, with Amy finally realizing that she needs some sort of balance in her life, just as Colin takes a turn for the worst. The WB may have gone into this looking for another Dawson's Creek type teen soap opera. There's certainly that aspect to it, but there's a whole lot more.
