The Fool is the most complex and most contradictory of all the Tarot cards.

The number zero is usually associated with this card. In fact this is simply a shorthand for saying that The Fool has no number. He is outside of such systems: "I am not a number, I am a free man". As such this card can be considered to fall at the beginning of the major Arcana, or at the end, or anywhere in between.

The Fool represents naivety and childlike innocence - yet the Fool is wise.

He carries only what possessions he really needs, having thrown off the rest of the materialistic baggage that we carry. He journeys through life, tasting everything it has to offer then letting it go and moving on.

In many Tarot decks The Fool is illustrated as being about to step off a cliff. Is this symbolic of dangerous, impulsive risk-taking? Or does it indicate one who simply refuses to be held back by the problems life throws in our path.

Whether the Fool represents opportunity or danger one thing is clear: this world needs more fools.

I was conflicted in the character choice for this one... should I use Sam or Jo? The path through the tarot is often called the story of the Fool and since the story of Supernatural is supposed to be the story of Sam... that seemed like a natural choice. However, I didn't want to double up too many characters on the cards and Jo seemed like a natural for this card.

Obviously, I chose Jo. I thought her youth and inexperience paired well with card and she’s shown a propensity to charge in without thinking. Sam usually only does that when Dean is in danger. Tasting life and moving on is also very Jo, she yearns to get out and to be a hunter and gain experience. All in all, I felt that she better represented the blind push forward that I think of when I get the Fool card in a reading.
