That's a good point Andrew, one I hadn't thought of.

I did post some speculations on Origins of Mercury, but I hadn't considered that kind of foil-ing (fighting evil versions of the other person? Genius!).

Which means if I were to expand upon it...

If Roman and Weiss appear to have similar personalities and fighting styles, then Roman and Blake seem to have the most opposite ideologies: one is a human who hate faunus; and the other is a faunus who wants humans and faunus to get along.

I had guessed that Emerald has a "laid back" attitude to contrast her with both Weiss and (my guess of)Mercury; but if I were to speculate as to how Blake and Emerald are similar, then the two of them might come across as "aloof": sitting back and listening most of the time, then commenting on what other people say; and when they do speak, they rarely say more then thy need to(you know, compared to Weiss and Roman, who tend to let their mouths run when they start talking).

As for ideology... hmmm... hrmmm... Well, if Weiss is disgusted by her family's "questionable business partners", then Roman is representative of these "business partners". As such, if Blake is disgusted by White Fang's "extreme methods" then Emerald is representative of that "extremism": Emerald may be willing to anything no mater how morally reprehensible, to "get the job done".

Well that was a bunch of poorly-aimed shots in the dark; If anyone feels I goofed, feel free to rip it apart.

Oh, and I linked to my previous speculations because copy-pasting a long post onto a long post seams a bit counter-productive to me. You might want to look at what I speculated before to understand where I was coming from here. Or don't, totally your choice.
