My love letter to the JN fandom and the Western genre. Have you ever wondered what the cast of Jimmy Neutron would be like if they were born and grew up in the mid-1800s? You probably haven't — but I have. So come on, step right up. Feast your eyes upon the JN fandom's only Wild West AU, because there's no fanfiction niche too small for me to fill.
SYNOPSIS: Rail Baron Eustace Strych hires a notorious contract killer to murder an old foe, but she finds herself intrigued by the man she's meant to eliminate. Unbeknownst to her employer, she offers her target a chance to save himself. [ILLUSTRATED]

Summary
Robert Chase clocked in to work, his morning coffee with Foreman and Cameron the same as usual as the three waited for House to show up. When he does, the case file in his hands turns out to be not a usual one, rather that of Billy Kennedy - a kid who looks eerily, eerily similar to Chase himself.
It only escalates as more look-a-likes begin to show face, as if called by fate.
