Henry: I'm from Normal, IL. 1958.
Dean: Right. Seriously? Dude's time traveling through motel-room closets. That's what we've come to?
Henry: You're men of letters, correct?
Dean: I'm a little rusty on my boy bands. Men of what?
Henry: My father and his father before him were both men of letters. As John and you two should have been. We're preceptors, beholders, chroniclers of all that which man does not understand. We share our findings with a few trusted hunters--the very elite. They do the rest.
Dean: So you're like Yodas to our Jedis. (Henry stares blankly) Never mind. You'll get there.
Henry: Hand me your... walkie-talkie.
Sam: You mean my phone?
Henry: Even better. Operator, I need Delta 457.
Dean: Who are you not calling?
Henry: I'm sorry I judged you two so harshly for being Hunters. I should have known better.
Henry: You're also Winchesters. As long as we're alive, there's always hope.

Referencing the Back to the Future movies (1985) starring Michael J. Fox as Marty McFly, a teenager who travels through time using his mentor Doc Brown's (Christopher Lloyd) time-traveling device, mounted in a DeLorean. Marty goes back to when his parents first met, similar to what happens here with Dean. Also, the scene where Dean first encounters his dad at a diner is a near reenactment from the movie. In it, Marty was unaware that the man next to him was his dad, until someone called their last name and they both turned around. And the man that visits Lydia is Dr. Brown.
