Im so sorry
It makes me incredibly sad that the show, intentionally or unintentionally, has seemed to establish that Sam really has no real connection to his Father or his Mother. They've gone out of their way to show that Dean is a Mary clone. And although it's been pointed out that Sam is like John, he barely had anything but a contentious relationship with him. Jared's portrayal of Sam's obvious need to be understanding and ...good, I guess... whenever she's around just breaks my heart.
