One testsub was picked out by Dr. Ulti, to break myths. Fish "Edward" was involved, but was not alive. The testsub was placed in the containment cell, and ordered to wink.
The testsub winked as O-173 teleported from the other side of the room to the testsub, almost causing O-173 to snap the test subject's neck.
It is now proven that O-173 reacts to winking, and considers it as cheating.
Fish "Edward" was laid in the middle of the cell, and the testsub was ordered to go to a safe corner in the cell and blink.
Fish "Edward" had no effect on O-173, even though the eyes were open.
The test was ended. All test subjects were alive and well, with an exception for fish "Edward".
