Amy gave the group a cautioning glance.  They had to be patient, whatever it cost them, and wait until the man was well inside the room before they acted.  If he was able to retreat, everything would be ruined and they'd never get another chance.  So she watched, trying to look the picture of a frightened prisoner, as the door opened and their captor stepped inside.  Once he was well and truly inside, hopefully distracted by Jenn's performance, they could strike.
