    Summary

    After realizing that he knows next to nothing about how Ink came to be and that the guardian knows nothing as well, Error decides to start looking into it. The Creators are egging him on, and shenanigans from the other outcodes are proving to be quite the distraction; Ink just wants to be his friend (not happening), Dream is acting weird, and Nightmare can't believe his eye. The chances of Error learning everything are slim-to-none, but since when did that stop him?
