tarot lessons but relate it to nbc hannibal because that's all your brain can process:
the fool: hannibal trusting will in season two can certainly be a representation of the fool. it is an exciting, marvelous feeling, to jump right in, blindly, trusting only your heart, but it has risks. but the fool is a card that tells us about intuition, too. so don't be fooled by the fool, it might be impulsive and too optimistic but the truth always comes to him. he will eventually see things clearly. yet, even so, if the fool remains in this same state, he goes right back to hannibal in the ufizi gallery...open, trusting. the fool always manages to find the truth behind the illusion, yet it might still choose the illusion, not because it enjoys it, but because the fool believes the illusion to be a truth. the fool is a fool not because he's stupid. he's a fool because he refuses to look (as in the card, his eyes are looking up instead of ahead, towards his path). there's an arrogance disguised as optimism in the fool. it cautions about lack of discernment or planning ahead.
spiritually it is the seeker taking his first step towards the abyss, convinced the journey will be rainbows and butterflies, but mostly convinced that who he truly is, is the ego.
hannibal as the fool is hannibal realizing that love changed him, and he is not who he thought he was. fortune's fool? no, yours.
