Not culture is but is there a term for a cyclogenic type of headmate that keeps coming back? Like they are similar and fulfill the same role/job but they arent the same headmate as the old one
We may have misunderstood (followup asks are welcome, if you'd like to add more context), but the closest term we've found is Open Circuit — a headmate in a circutien system that keeps coming back or "reoccuring", perhaps with links to previous headmates or past iterations of themselves.
Other words that give us similar vibes, but didn't quite fit:
Backmate - Describes someone who was previously dormant, but has returned.
Rebornative - An introject of a dormant headmate, who may also be fused with, or an aspect of, that headmate. They may feel a deep similarity to their source while considering themselves seperate in some ways.
P.S.: If they identify with the "Came Back Wrong" trope, there's an archetrope flag for that!
