Ok, so the idea of a "trigger word" was it is a word that if said around a certain character it would make them remeber a bad memory or act in a certain way, (kinda how if you say f*ck in front of a really strictly religious mom that probrably is a Facebook karen) examples of some "trigger words" and sometimes they can be "trigger actions" and what character they effect are:
Unknown- if she sees a peachy/coral like color she will get really sad, if someone yells at her/talks louder than they usually do she will say I'm sorry over and over again and/or start crying, and a "trigger word" for her is "cara" or (not all the time) "mom"
Aqua- can't even be close to any type of gun without seeming slightly scared and if he hears shattering glass he will look really scared and frantically look around, his "trigger word" is "police cars"
Milo- dosnt like food, in general, they don't like eating it, the don't like being around it, or the smell of it (some foods Milo dose like the smell of but only like 2 or 3) if Milo is being forced to eat anything they will simply walk away, and if they do eat anything, no matter if it's good, bad, expired or fresh (some exceptions to this) they will gag (continued in next comment)
