#syntax x did reader

It was a bit confusing trying to talk to you and then all of a sudden you were going by a different name, maybe even a different GENDER, and were talking as if you barely knew him

It turned out you were understandably extremely anxious about revealing your status as a System to him

Though he wasn't overly familiar with OSDD/DID, he went looking for the few available resources that weren't littered with bias or ableist language (no small feat)

After this he decided it would be best to treat each alter like a new person, first asking if they recognized him before introducing himself and explaining his role in the life of the alter(s) he knows

Of course this doesn't diminish his feelings for you in the slightest

If anything he now sees that he must win the affections of every alter (except if they're age regressors/littles/kids of course)

While definitely not the best with kids, Syntax did decide that he could suck it up for your sakes. Through trial and error and lots of questions, he figured out how to act as a proper caretaker for the little alter(s). Though intimidation is his domain, with you all he can't bring himself to be as stern

This has the effect of anyone who scares the System or upsets them being faced with an extra dose of his wrath

Of course he'd never let you see what he does to the offenders, he doesn't want to upset you so badly you form another alter
