Who might the other two SMCs that most wanderers on Earth incarnate from be?

I can't remember WHERE in the LOO material, but in it, Ra explicitly states that VERY VERY rarely, an early 6D negative will choose to incarnate as a wanderer to gain negative polarity, and that this is extremely uncommon. Nonetheless, it happens. And from what I was able to tell, in the INCREDIBLY RARE event of a negative wanderer, it will most likely be early 6D. Like Ra said though: extremely rare.
