youd think theoretically id would be supervision. especially since a potential abusive person is much more likely to get triggered by something out of line if it's related to their leading function. so, say an SEI does something stupid with taxes for example and it pisses off their spouse whos LSE. the LSE would get more pissed off than if they'd married an LIE instead whos less likely to mess up in the same way.
sure, the LIE LSE pairing might still have a slightly abusive relationship because the LSE would inherently be a bad person, but would it be as bad if theyd married the SEI?
