OK, I find this absolutely HILARIOUS. I just came to these boards and after spending some time in the Bella and Edward threads where there's much angsting and questioning of motives, etc., it's quite amusing to come in here where, as I suspected, it's all about the love! Much like Seth himself!
I can kinda understand what HOFJ is saying about him being 2D, since there's basically just pages and pages of everyone saying they love Seth, but I think his character served an absolutely essential purpose in BD. I mean, the three main characters are basically going through the worst hell of their lives and just trying to cope with it the best they can while making huge life-changing decisions. Seth was a little ray of sunshine. Our comic relief when nobody could really be funny (well, Jacob's chapter titles were ROFL funny, but you get my point).
I mean, Lord knows we needed the "Edward are you there?" and "shutting" for OUR piece of mind, while he also helped Jacob's piece of mind, and, I think, Edward's. He also really helped Jacob step up to the plate in terms of being an Alpha. That middle part of the book would have been just one huge downer if not for Seth and his "oh no way! That just plain ol' sucks rocks!" (or something like that) when Jacob is considering something as horrific as having to kill Edward.
