#2: Why Gendo Never Goes Outside

Gendo Ikari, the commander of NERV, seldom went outside. For the same reason he also used waterproof soap and drank only heated beverages.

You see, Gendo had a certain problem. One he did not wish anyone to find out about. Gendo stayed indoors so much to stay away from all the accidents concerning cold water that had plagued him ever since his return from China. It would not do for anyone to find out that the Commander of NERV turned into a small black pig when splashed with cold water.
