* [[ParanoiaFuel The Looper business model.]] You're young and your prospects are limited. Working as a looper is high-paying, easy work in a CrapsackWorld. There's a catch but it's so far away you don't even care. Then one day your paycheck is a different color and it means there's a very special person under that bag on their head. You can take your money and run as far as you can but you know that [[DeathsHourglass someday, ]][[ForegoneConclusion somehow,]] [[StableTimeLoop that person is you.]]
