12x22 Who We Are
First Aired: May. 18, 2017 on The CW
Summary: Caught in a dangerous situation, Sam and Dean only have each other to rely on. Meanwhile, the fight between the American Hunters and the British Hunters comes to a head.
- SPOILER: Walt and Roy in this episode are the two hunters that kill Sam and Dean in S5 E16.
- In the episode, Dr. Hess calls Sam "Dean" by mistake, and Sam corrects her. This could have been a nod to Gilmore Girls (2000), where Jared Padalecki plays a character named Dean.
- The first two hour season finale since season 6.
