When we first discovered being a system, one of the alters we suspected we had was Silly (that's parties name) and a few months after, we stopped believing party was real and removed Silly from the roster.
We believe this was because during our syscovery our hosting situation was actively changing and evolving into me, The Paradox, and so finding out who was real or not and whatever was difficult. We were also actively in a harmful relationship, doing school, and discovering A LOT about ourselves on top of going through new traumas we had never faced before.
Yesterday, after some deliberation we finally concluded Silly WAS actually a headmate but was apart of my subsystem, we didn't even believe we had subsystems when we first started our journey so the idea hadn't occurred. Now we welcome Silly back with open arms and luckily XD isn't mad at us at all, I don't think XD would have the heart to be anyways. This rediscovery alone has given us a lot of peace again, especially since this realization came after KO and I were having a huge fight in the front, and after Lark got it settled, things just felt better.
