Tiger T

Professor T becomes embroiled in a hostage situation, but his unconventional negotiating tactics do not go down well with the police. Old flame Christina reveals all is not well with her marriage.

Professor T color codes tea bags in the police station while explaining how black diamonds, or carbonados, are thought to be created with the team. He later meets Ben, but the two quickly clash when Ben refuses to follow Professor T's three rules for hostage negotiations and leaves a used tea bag on the once-clean table.
