Can we talk about Mary and Sam? In a single episode, Mary cycled through a lot of the things that have haunted Sam at certain points throughout the series—not feeling like she belongs. Admitting that the place others call “home” is not her home. Loving her family dearly but needing to seek a place where she can find herself. Feeling like she’s the odd one out in a trio. Mourning the loss of a loved one. Being left behind in hotel rooms while the others go out and hunt. Mary Winchester is a powerful hunter, but she’s empathetic and intuitive and seeks the truth behind the easy answers… like Sam.

Also like Sam, she spoke to her family and said she had to leave. 

Like Sam, she faced rejection born of pain when she expressed her need to leave.

Unlike Sam… Mary Winchester has a son named Sam, who has been through all of those things, understands them intimately, accepted her decision, and had the strength to put her needs over his desire to have her beside him.

Sam Winchester, giving to others what he never received.
