Plural is an opt-in label. It means more than one. The minimum count is 1*, not even 2. The not-quite multiple are who plurality was meant to include. It’s not being overt or separate or amnestic or distressed that makes you(&) plural, because diagnosis is irrelevant and those are all criteria. Median and midcontinuum folk are as plural as anymany. Only you(&) get to decide whether you(&) count.

It is sort of astounding how real plurality is

One moment you can only be feeling one emotion, the next moment, that emotion is so foreign to you that you struggle to imagine why you would ever feel it, and what it would feel like.

your system literally can look like anything. it can have only introjects, it can have no introjects, it can have only non human members, it can have only members that look exactly like the body, it can have only littles, it can have only ageless members, it can have a full system of members that all have only one type of role, it can have a million members, it can have only two members. there is no set way systems have to look! they can present however your brain deems necessary for you!
