ha, that's probably accurate too..
As for the OP, I know we're not really talking about Vedic astrology, but some believe that Rahu is co-ruler of Aquarius (along with Saturn). This makes the most sense to me.
From
http://www.barbarapijan.com/bpa/Rashi_Lagna/11kumbha_lagna.htm (Kumbha is Aquarius, Rahu is North Node, Shani is Saturn):
In Jyotisha, the Kumbha rashi has TWO planetary rulers and they are utterly apples- and-oranges incommensurable with each other: Rahu + Shani.
Way too much from the link for me to post here, but it's definitely worth reading if you want to understand just how Saturn's energy "works" with Aquarius. And perhaps why Aquarius is so different from Saturn's other sign.
