At the moment of his rescue, Captain Picard finally agreed to the number of lights he was told to see. These people would never think of holding out
Close. As they came to take him back after Capt. Jeico threatened to blow up a bunch of their ships he screamed “There are FIVE lights” which was right.
Later he told Counser Troi he would have said four because he was broken.
I’ve watched too much Star Trek OS and Next Generation.
