Okay, this explains what I was trying to say in proper english

They're quotes from the net:
The Circle (aka
): "Simplest shape of all, and manifestation of the
One ... It is the first expression of Universe; a horizon, a boundary between Self and Other."
"The Circle is a picture of the Sun and was the symbol of the Infinite One. The circle having no beginning and no ending also symbolized:--everlasting, without end and infinity."
--- Makes sense Speedy's number 1, as he's the leader.
The Triangle (aka
): "A triangle is a statement about relationship and balance ... the ancient mathematical philosophers referred to the Triad as prudence, wisdom, piety, friendship, peace, harmony, unanimity, and marriage. We see this balanced path between extremes in periodic phenomena such as a swinging pendulum and a heartbeat."
"The Triangle represents the active principle and is often used as a symbol of fire. It's energy is dynamic and it creates change, moves forcibly and with power."
--- A triangle is also
Three, and a triangle pointing down (which Polly has) represents inner development ... and also the element of water. But I think of Polly as more like fire?

Then again, apex down triangle symbolises woman/feminine/creation.
The Pentagon/Pentagram and the Golden Proportion (aka
): "The four terms of the square are enough to account for the idea of matter, or substance. But when we get to
Five we introduce the concept of Spirit, or governing intelligence; or in other words Life. Five is seen as the union of Two (female) and Three (male). Thus the five-sided pentagon and in particular the pentagram star within it symbolises life and regeneration."
"The number Five has always been regarded as mystical and magical, yet essentially 'human'. We have five fingers/toes on each limb extremity.We commonly note five senses - sight, hearing, smell, touch and taste. Five were the virtues of the medieval knight - generosity, courtesy, chastity, chivalry and piety as symbolised in the pentagram device of Sir Gawain."
--- Guido's definitely a chivalrous/knightly kinda guy. Chastity? Don't think he'd like that some how ...

.
Hmmm ... maybe there is something in this. I also noticed a pattern: Speedy, Polly and Guido seem to all be represented by odd numbers - each a digit apart =
1,
3 and
5.
Any other thoughts? Does this help answer the question?

If you wanted to know more look up sacred geometry or numerology. The definitions are endless! Brain freeze is likely.
