Although Dean made me really freaking sad by being so utterly destroyed by it, I think the fact that Dean actually went to Hell when he died made it a bit sadder (because I feel like Sammy went to Heaven)

I was the saddest when Sam died because of how Dean was affected by it, and I didn't know Sam was going to die like we did with Dean for a season.

Because I missed the episode Sam died and I read about it later so I didn't cry at the episode itself. And I read about Dean making the deal on fanpop and Sam coming back so he wasn't really dead to me. But I still think;

Winchesters just shouldn't die :'<

its still hard to watch AHBL for me sometimes Dean's pain just makes me want to give him a hug every time i watch it

Because of Dean's reaction to it.
