User blog:ImperiexSeed/Oh how characters underestimate Lucifer

In multiple episodes on multiple occasions, many characters, including Gabriel, underestimate Lucifer, and his capabilities.

Zachariah abruptly admits that Dean alone couldn't dream of killing Lucifer, as he reminded so many times in Season 4, and only through Michael could he stop Lucifer. Dean does, however, at the end of "Sympathy For the Devil" admit that he and everyone "don't stand a snowballs chance".

In "The End" and "Abandon All Hope", both Cas (even after calling the act "insane" and "impossible" the episode before) Crowley believe the Colt can kill Lucifer, man how wrong they are.

And in "Hammer of The Gods", Gabriel says Lucifer doesn't know about the keys to his cage, but he actually does.
