Sadness

I just finished watching Supernatural 2x17 "Heart" and it was the saddest Supernatural episode I've ever seen :(

After all Sam and Dean tried to do for Madison to save her from being a werewolf [ie killing the one that made her into a werewolf] nothing helped and Sam [who had a thing for her] was asked to shoot her while she was human because she didn't want to kill other people in her werewolf-form. I don't think I ever saw Dean cry... And with tears in his eyes, he shot her... [you didn't see it, but you heard the single shot, which probably made more of an impact on me]
What a terrible thing to have to go through...
