Two lefts and a right, ventilation shaft, ventilation shaft where the hell are the ventilation shafts? Or the fucking storage closets? or ANYTHING? This base is bullshit and he starts taking his turns in- well. The Fibonacci sequence. Something he and Delta sorted out as a mental shorthand for getting shit done, even was left, odd was right, every third even or odd was straight.

Convoluted- yes. Seemingly random with a logical progression they and only they understood? Definitely. Wash doesn't have D- Delta's dead.

So it's a safe enough habit to fall back into while he works the cuffs open bit by agonizing bit.
