"Yes they should! The love story between Dean and Cas has me completely hooked. Even though it's epic and takes place among angels, demons, gods and monsters, the feeling between them is still so recognizable and relatable – quite simply it feels just like the love I have for my own family. I started out as a Sam girl. I identify with Sam because he's brainy and moody. I identify with Dean because he's coming to terms with his bisexuality in his 30s, just like I did. I identify with Castiel because he's so earnest and wants to do good with a hint of the autism spectrum.
I don't watch just for the brothers, I watch for all three. And Cas has actually become the glue of Team Free Will. It's no coincidence he was there on the bridge in the final scene of Road Trip, where the brothers split up. Cas embodies the bridge between them, the guiding light for them to find a way to BE brothers in a good way. And especially for Dean to be the man he wants to be.
TV Guide, it's nice of you to mention this pairing's enormous, passionate, extremely active fandom. Just an observation, btw: The other 19 pairings in this TVGuide article have maybe a few hundred votes at most, and a handful of comments for each. Destiel is already at almost 21,000 unique votes (only counting the yes votes) and 1,700+ comments – overwhelmingly positive ones. Supernatural showrunner, are you paying attention? You have in your hands the hottest commodity in American TV right now. Handle it right. :) "
