Kate, in fact, starts sucking wind and Kate tells her that she should take the lead and set the pace. They make it to the roof with time to spare and decide to make a guess as to which watch it is. They opt for the silver with the stagger sweeping hand as the fake watch. At the rifle range, both watches are lined up for their own execution. Once the watch is shot, either red or green ink will squirt out on the target.
Green ink means a successful mission.
In a single shot, the watch is destroyed and green ink splatters against the target. Back at home base, their success is applauded by their cohorts. What is most interesting about this challenge is what went on when seemingly no one was looking. Charlie, alone outside the compound, is peering inside a production van. He opens the front door when a voice tells him he shouldn't be doing that.
