After Afghanistan, everyone with a certain clearance level expects Tony to have a problem with water. It'd be logical, given all the psychological issues or human wxamples.
Tony doesn't have a problem with water.
He lives by the ocean in Malibu, with a view of the ocean in New York, he drinks clear water all the time, likes walking in the rain and getting wet, long showers, swimming pools.
There was no luxury of bathing inside the cave, just quick superficial washing with old water from a bowl, so the feeling of fresh droplets falling down and touching, caressing he skin, just takes some time to get used to. It was never exactly fear, it was just – discomfort. Because every time the terrorists put his head into the water Tony knew it was just torture, he knew it would end. He knew his brain was more precious than anything else and no one would risk destroying the treasure.
But when he escaped and walked for some hours through the desert – he still doesn't know how long – there was nothing but the driest air of all, the desert air, and he knew that if he died, no one would even know.
