Master exploits Trenchard's cooperation

The Master coldly manipulates Colonel Trenchard despite his assurances of control over the Doctor and Jo Grant. While Trenchard boasts about securing the Doctor and dismisses Jo's escape as contained, the Master detects weakness in those claims. He abruptly pivots to demand direct access to the Doctor, revealing his true priority lies not in containment but in exploiting the Doctor's presence to advance his own sinister ends. This calculated shift exposes Trenchard's unwitting role as a tool in the Master's grand strategy.
