30. In the final battle with Lucifer, what object saved the world?
From Quiz The End- Pt.31
Answer:
the Impala
An narrated by Chuck the Prophet (aka as Carver Edlund) in the finale, the Impala was the most important car in the whole universe.
Chuck: "On April 21, 1967, the 100 millionth GM vehicle rolled off the line at the plant in Janesville--a blue two-door Caprice. There was a big ceremony, speeches, the lieutenant governor even showed up. Three days later, another car rolled off that same line. No one gave two craps about her. But they should have. because that 1967 Chevrolet Impala would turn out to be the most important car--no, the most important object--in pretty much the whole universe."
It was the car, and all the memories Sam had tied to it, that allowed Sam to take control over Lucifer. He opened the portal to Lucifer's cage, and began walking him to it. Michael arrived, after having been sent away with holy fire by Cas, and tried to stop it from happening. Instead, Michael (in Adam's body) got close enough for Sam to yank him down into the hole as well.
