Aliases Ficathon Entry: "Thimblerig"

For kerlin, who asked for Vaughn in a US Navy uniform (mad bonus points for officer's dress whites...), Syd/Vaughn and Jack glowering.

Thanks to taiamu and synaesthete7 for their betareading and support.  And thanks to J.P.J., CDR USN who answered my silly uniform questions. 

The setting is sometime during S4 (or reader's choice, really, it's not specific).
