Extrotim Ethical types as escort chicks/dudes
I think, each quadra has his own image-giver. EF types are really good at this, as they're statistically the most good-looking and friendly.
EF types are easily recognisable : they seemingly tell others to join their quadras.

ESE's are here to make Alphas look friendly, playful, bold, independent, and super fuckin' cool !!! because you know, the whole essence of Alpha is coolness. That's right. Alphas are the coolest and the friendliest quadra of the whole socion. ESE's are VERY friendly, and make Alphas look less nerdy ; or they may even support such nerdiness.
Ethical Intuitive Extrotim
EIE's are here to reflect Betas' drama, idealism, and maximalism. They are very persuasive creatures that are able to manipulate even the most tough-minded people (i.e. LSI's). EIE's are very zealous people. Think of the Baroque style - a perfect example of the Beta thing.

SEE's are here to make Gammas look less sad, critical, and hostile. In fact, SEE's are usually friendly (though I think they're boring and overwhelming). SEE's are usually outspoken, loud, heavy-handed, bubbly... pretty much like EIE's. Except that they are more inclined to a quantitative, realistic, material way of living rather than the ascetic idealism of EIE's.
Intuitive Ethical Extrotim
IEE's are here to make Deltas look less machine-like or overly serious. IEE's are usually open-minded, energetic, friendly, and lively. They see life as an adventure which is full of options. They are very social. That's right. Other Betas aren't very social, nor very energetic, even if they're comfortable or agreeable. IEE's make Deltas look less boring, because most people see Deltas as friendly, but boring.
