The post has been made, the retcon has been completed. If there is one thing I hate more than someone making a character to not post, its that person leaving the RP after having their character interact with the RP. Sure, you can go the route of just pretending that never happened, but that looks weird, and when someone outside the RP reads the RP it looks horrible. So, a good GM retcons the character in a way that makes sense to the story. Hopefully what I did makes enough sense to the story to not look completely out of place.
