Is it so hard to believe Dean really loves Tori?
There are some people out there who think that Dean is only with Tori for her money and fame (like my Mother). I think most people who watch the show, see that Tori is wonderful, funny, caring, sensitive, and an incredibly sweet person with a heart of gold - and might I say she is very attractive. Is she Angelina Jolie in the looks department? No - but she is very well groomed, has a nice thin body and looks great in clothes. If she was walking down the street, you would definitely look at her even if you didn't know who she was.
If all of us - especially the overwhelming majority of people on this board who didn't care about or like Tori before the show have learned to love and respect her, why should it be so far fetched that Dean loves her too for all of the reasons we do. She also seems to have some very caring friends who love her for the right reasons too.
