As most people know, the narcissist observes and analyzes their victim’s behaviours to utilize as a generation tool for supply. It is important to know what those triggers are to avoid going down the rabbit hole.
The narcissist will deliberately and covertly attempt to trigger you in all sorts of unimaginable ways, all deriving from how you have behaved and reacted to various things in the past. The narcissist behaves in this sorta of robotic way in that sense, behaving in a automatic manner based on what he/she has perceived.
This can be used as leverage for the victim or as a generating supply tool for the narcissist.
