Seth is one of my very favorite characters of the series. He is open to anything, because he hasn't been jaded by much yet regarding the vampires. In many ways, I like him better than Jacob. He does not frustrate me as much as Jacob tends to in the later books. Seth takes the qualities of the younger Jacob, in Twilight and part of New Moon. He's the innocent kid, with a wholesome mind, so says Edward.
I have a recurring joke in my family. When I was 5, we went to Disney World, and I really wanted to stay an extra day. My dad said he would make a deal with me. If we stayed another day, I had to let him pick out my husband when I was older. As a five year old, I reportedly (because I have little memory of this, and my parents remember this all too well) looked at him kinda funny but then said of course sure daddy! Every once in a while, he'll jokingly bring this up again. When he finished Breaking Dawn, the first thing he said was "I've found the perfect guy for ya, Kate." I looked at him funny as I did as a 5 year old. It seemed a pretty random comment to say after reading BD. so I said "ok, then, who?" and he said "Seth Clearwater" with this smirk on his face. So now the prospects have gone from Mickey Mouse, to Donald Duck, to Jake Ryan on 16 Candles, and now to Seth Clearwater. I have to say, he does seem like a great guy, the first time i've EVER agreed with my dad on this topic. Too bad he's fictional!
Kaleb Nation is awesome! Check out his site for insightful comments as he reads New Moon.
