We've got some kind of trauma, we're not sure what, but we think it gave us cPTSD. Anyway.
We get really triggered around anything involving externally changing someone's identity, including mindwipes and the like, and a lot of corruption stuff. (Consent helps a lot here.)
And we get **massively** triggered by person-merging/fusion. Seriously, it's... just, no. Even with consent it still /heavily/ squicks us out (not much else does).
