This week's episode of Supernatural is really interesting☆
Castiel brought Dean back to the past.
The year 1973, to be exact, back to his family hometown of Lawrence, Kansas.
He met his father at a diner who treated him to a cup of coffee. In turn, Dean convinces him to get the 1967 black Chevy which will be handed down to him many years to come.
Later, he was invited to his mother's house for dinner with his grandparents,
whom he had never gotten to meet before.
It's hilarious that Dean was named after his grandmother, Deanna (lol)
Whereas, Sam was named after grandpa Samuel.
We also found out his mother, Mary was born to a family of hunters.
So it wasn't in his father, John's nature to hunt down demons & other supernatural beings.
Castiel revealed that Yellow-Eyes demon, Azazel had some big plans which had to do with Lucifer's freedom. He's the bad ass who killed Mummy Winchester in the first season.
He'd apparently covered his tracks well, which led Castiel to bring Dean to the past to find out what he had done. In case you didn't know, Dean killed Azazel in Season 3. o(^o^)o
To summarise the ending:
Pre-hunter John was killed by Azazel. Mary made a deal with him to bring her boyfriend back.
In return, he gets permission to enter her home 10 years later.
(10 years later, Mary would die while trying to save infant Sam)
Man, this episode was soooooo good!! (^-^)v
Sam only appeared for 5 seconds, which I really don't care. (lol)
The episode ended with Castiel telling Dean that his brother is heading down an evil path.
If he doesn't stop Sam, Castiel may have to finish him off. (゚ロ゚)
By the way, Misha Collins aka Castiel is starting to grow on me~.
