The writers manage to take us through all 22 Major Arcana. For those of you not familiar with the Tarot, there are 22 Major cards, and 56 minor cards. The 56 minor cards correspond to the modern day card deck, with four suits. Each of the four suits has four court cards (king, queen, knight, page) and 10 "number" cards from ace thru ten.
The 22 Major Arcana cards each represent an archetype. Click here to see all 22 Major Arcana as presented by Bitter Suite.
The Tarot images don't come into play until the dream sequence starts. I thought Callisto looked like the FOOL, but brushed it off. I sat up when she spun the WHEEL OF FORTUNE, but then was totally captivated when Xena turned into the HIGH PRIESTESS.
Anyway, after two viewings, here is what I come up with. I'll put a brief "meaning" of the card in parentheses. Love to hear your feedback.
Callisto
opens as the FOOL (beginning of the journey, what you create
is up to you) -- the words of Callisto's song play on this.
Callisto
turns into the MAGICIAN (the Magician manipulates the elements,
juggling them in the air and balancing their antagonistic energies, showing
the possibility of guiding -- and being guided by -- the archetypes).
Callisto continues this role as she begins playing with the chakrum/wheel, which
finally turns into...
The
WHEEL OF FORTUNE (the revolution of experience and progress)
-- which Callisto forces Xena to spin. This is the wheel of birth, death, and
rebirth, to which all souls are bound. It's the wheel of karma. To master your
destiny, you must understand the process of life and death, cause and effect,
from the center -- not from the periphery of the wheel. By
the way, at the four corners are the symbolic figures of the fixed zodiacal
signs: the bull of Taurus, the lion of Leo, the eagle of Scorpio, and the man
-- or Gabrielle -- of Aquarius. The sphinx rides above the wheel, the snake
and the dog spin on the wheel.
During this sequence Xena is depicted as the HIGH PRIESTESS (Juno, Diana, the priestess of the Eleusinian mysteries, etc. She is shown in the vestments of Isis, a crown of two horn-shaped crescents astride a lunar orb, a solar cross on her breast...) The High Priestess is the potential uniting intelligence of subconscious memory. In other words, enlightenment to illumine the darkness of nonunderstanding -- and the way is through the Priestess, intuition, revelation, mystery.
Now
we jump scenes, with Joxer playing the HANGED MAN, pulling
Gabby out of the water. Yep, there he is, hanging upside down with one leg crossed.
Water is a symbol of emotional life, as a transmitter and medium for feelings
from the unconscious, which flow into forms made available for it. (The hanged
man represents how feelings actually hold us up by their apparent reality.)
The Hanged Man is also about spirit moving us towards initiation or understanding.
Transition. Undergoing initiation or revelation or mystery in order to
transcend outmoded forms of behavior. Sets us up for what is about to happen.
Gabrielle
emerges next as the EMPRESS (great goddess earth mother, with
dominion over the natural world). Perfect here with attendant images of villagers,
farm, harvest, family, nature. The Empress is about following the path of harmony
through conflict. Nurturing. Perfect for Gabby.
We
flip back to Xena, who has been joined by Aries, who sits on his throne as the
EMPEROR. (In Tarot, the Emperor is Aries, the fire sign, manifesting
self-assertion, authority, power.) 
Xena
loses her clothing, and in her new attire becomes the HIGH PRIEST
(an opportunity to transform material desire into higher understanding; ceremonial
traditions bring guidance to worldly affairs). The symbolism on Xena's new garb
is great.
Back
to Gabrielle... she is taken off old Mr. Donkey and given a scythe. I believe
this is DEATH (loss leads to renewal; letting go of possessions,
ideas or justifications). In the struggle to follow, Gabrielle throws the first
blow -- aiming her scythe at Xena's head.
Xena,
for her part, is now moving forward toward Gabrielle in the CHARIOT
(in traditional decks the chariot is drawn by two horses or two sphinxes with
exaggerated bodies). The Chariot is symbolic of the body drawn by conflicting
emotions. 
Xena
kills Gabrielle. Joxer shows up as the HERMIT (a wise man,
wearing a hooded cloak). The Hermit is about retreating from the world in order
to attain wisdom. The flame at Gabrielle's face may be a reference to the ancient
who prowled the earth with his lantern, always searching for truth.
Xena
and Aries go into a hot dance number, Xena in her red dress. They are the LOVERS
(rather than signifying sex or romance, the Lovers card signifies that a choice
must be made. Indeed, Aires is trying to woo Xena back to his side, and she
is tempted. Then as she slides to the floor, she turns to Gabrielle -- who represents
the virgin. In the traditional Lovers card the hero has a temptress on one side,
and a virgin on the other. Only the innocence of the virgin, the true feminine,
can lead the hero to discover her individuality and wholeness.
At
the end of this little dance, just as Xena notices Gabrielle again, Callisto
shows up as JUSTICE (her clothes has the scales of Justice
embroidered on them; Justice is about learning that all imbalance comes
from within and that the restoration of balance also comes from within). Callisto
prods Xena on her way.
As
Xena is realizing what she has done, holding Gabrielle, Gabrielle's form appears
in the doorway behind surrounded by an aura of light. Gabrielle is TEMPERANCE
(a winged angel from Heaven, with a ring of stars or light around her head;
Temperance is about the eternal nature of true love, the eternal nature of life).
One meaning of Temperance actually states that temporary stalemate followed
by reconciliation!
Xena
and Gabrielle are transported to a new room or set, which I believe is evocative
of the MOON (this card usually has a pair of towers or pillars,
one on each side, which represent the rigid structures that develop from past
actions). Xena and Gabrielle must find their balance between the rigid structures
of their past experience. In fact, the echoes force them to forego yelling about
the past. By focusing on their feelings right now, they begin to overcome the
traps of perception and seeming reality.
During
this sequence, Xena and Gabrielle look up and see the TOWER
(total change and loss of security leads to a new beginning; the Tower card
usually shows a tower shattered by lightning). Imbalance builds to the point
where reality explodes, forcing Xena and Gabrielle to face the reality of their
dilemma. It is a trial, but one that will lead them to freedom.
As
they are figuring this out, the crypt opens. This is JUDGEMENT
(people emerging from coffins and graves). The coffin is indicative of life's
structure, that what we think of as reality is really a trap. Judgement is about
transcending this limitation -- and about the merging or integration of differences
between male/female into the child (where child becomes an image of unity).
Of course, a few frames beyond this part, Solon makes his appearance... the
image of unity.
But
before that, Gabrielle and Xena are dragged off by the fire arms of Dahak. Clearly
hatred gives him opening to the world. When Xena and Gabrielle are chained up,
they represent the DEVIL, so appropriate given Dahak's general
character and demeanor. (The Devil card is about overcoming the temptations
of the physical world -- especially temptations like hatred. Hatred is self-centered
behavior that traps the soul within the physical senses, cutting off spiritual
light and spiritual redemption). No reconciliation is possible until Gabrielle
and Xena deal with the hatred.
Gabrielle,
naturally, makes this leap rather easily. It is within her character to do so.
The scene of golden rain is the STAR (healing waters of heaven
uniting earth and sea). Healing blessings set Gabrielle free, but Xena is not
yet able to cross over. She still has to deal with her lie to Gabrielle. 
Gabrielle
at this point becomes STRENGTH (Diana, the virgin huntress,
overcomes destructive desires by inner strength -- by confronting herself, and
thus achieving self-mastery). Gabrielle is sure that Xena can follow this path
as well. Which she can, but only if she asks for forgiveness.Which she does, most beautifully.
The
focus moves to Solon, who represents the SUN (love and friendship
are equated with the warmth and creativity of the sun). Remember that the son/sun
represents unity. The Sun awakens the higher vibrations of spirit within, allowing
Xena and Gabrielle to experience their new found freedom from the trap of old
structures, old perceptions, old hatreds.
Gabrielle
and Xena land back in so-called real world. They are being washed by the great
ocean, the great earth mother. As they lay on their backs in the water, laughing,
the camera angle pulls way back. We see the image of the WORLD, the last and
final card of the Major Arcana. The World or the Universe, is success. By understanding
and living with spiritual and physical laws, Xena and Gabrielle have completed
a sequence.
