JJ Abrams and his love of nicknames

(or maybe just his writers?)

NOTE: SPOILERS AHEAD!

Examples:
Alias (season 4): "Arvin Clone" (imposter of Arvin Sloane)
Lost (all seasons): anything Sawyer says
Fringe (season 2): "Walternate" (portmanteau of Walter and alternate)
Fringe (season 3): "Faulivia" (portmanteau of Faux and Olivia)
