(spoilers..) what did Fallon mean by.....
Spoilers....
When he is talking to Juggernaut --"and you know what I am afraid of" , when he is asking him which wire to cut on the detonator cap for the bomb...Harris then waits for Juggernaut to tell him which wire to cut, and then of course figures out to do the OPPOSITE_-that the RED wire was the hot lead for the detonator--and NOT the "loop" wire--or "boobytrap" one--that went to the trembler switch.
What was Fallon referring to here? Something that went back to their days together in the service or such--and about the time one had made a mistake about that German landmine? Or.....was Fallon saying something about being afraid he would be "wrong" and then he would not be "the champion" anymore..and Juggernaut would win?
