Trevor’s act seemed to be working. The security guard pointed outside, took the two badges from him, and dropped them in the scanner. Trevor gave him a tearful smile, then jogged out the building after his "mother." As instructed, he didn’t look back at Carla and give the game away. Later, when security did a count of the returned badges, they would assume that all fifty-six members of the 5 p.m. tour had exited the building.
