S4E1: Roswell That Ends Well
Hey, and while we're on the base, I'll visit my Grandfather Enos.
He was stationed at Roswell. Your grandfather?
Stay away from him, you dimwitted monkey!
You mustn't interfere with the past.
Don't do anything that affects anything...
unless it turns out you were supposed to do it,
in which case, for the love of God, don't not do it!
