the sp blind 5 is not obviously disheveled, they keep a lid on their habits just like they keep a lid on everything else. it's when you manage to get close to them that you realize what you thought was an sp bubble is actually their perfectionism, especially when it comes to sx/so 5s, and their wax&wane attitude to their charges and passions.

the sp blind 5 may or may not get obsessed, but their obsession or lack thereof is accompanied by inaction, which is a direct consequence of the fact that they seek an unattainable ideal, a perfect theory that will never translate into real life and therefore rarely merits being acted upon. this is their self-rejection, the rejection of their own charge so as not to taint it. that's not to say that they cannot get incredibly interpersonally passionate; it's just situational and gets them overwhelmed really quickly, whereupon they retreat backwards in order to process that intensity.
