    Summary

    It's a normal day in the Underground, until Flowey meets a strange character that's shockingly similar to his favorite skeleton. The Bone Brothers say its their cousin, but he's not convinced. There was something more to this character...something that would prove obsession breeches the boundaries of time and space.

    This is my own interpretation of Underswap, based on vibes (and loosely on Dusttrust), so I apologize for any mischaracterization in advance.
