When the girls reach their room, the MI6 agent from London (Townsend) was there, having left the strong smell of cologne, coffee and footprints on the freshly vacuumed rug. At dinner, Professor Buckingham announces that Agent Townsend would be the new CoveOps teacher, and that Cammie's mother is temporarily detained. They quickly figure out that Agent Townsend is not interested in teaching at the school, but requested the job to help him find out more about Joe Solomon. They drugged him with an experiment Liz developed (A concoction 10 times stronger than Sodium Pentothal) and interrogated him, and they found out that Mr. Solomon killed Cammie's father.

She first slaps him, making him look frightened, and then she yells at him and tells him he got her father killed, to which he wearily replies, "I know." Agent Townsend shows up with a woman, whom Cammie believes to be the woman from Boston show up and Cammie discovers that it was a plot to capture Joe Solomon. She runs to a
