OOO2 - The Time Monster 2

This episode is the best of times and the worst of times for the Brigadier and UNIT. In reverse order, look at the Brigadier in the scene set in Stuart's flat. Has he ever looked more out of place than when he's standing stiffly amidst Stuart's collection of hippie artifacts and Elton John posters? He's then made to look very foolish by asking all the dumb questions, and not knowing when he's actually suggesting legitimate answers. The Brig has become a character, at best, endured by those around him - no longer in charge, no longer offering anything to the situation.

Then comes the brilliant scene outside of the TOMTIT complex where The Brigadier instructs the government types to keep schtum about what they've just seen, even quoting rules and regulations while doing so. That sorted, he then directs his attention to Dr. Percival, letting him know, in no uncertain terms, that UNIT is now fully in charge at the university. Attaboy, Alistair. It's good to see that you're honour isn't fully dead and buried yet.

Even Sgt. Benton gets in on the act, successfully fooling The Master into thinking that it was he who was actually fooled, then sneaking up behind The Master and (almost) nabbing him for good. Usually, UNIT's power has been seen through its artillery strength, but it is almost heartwarming to see that their recruits can be authoritative and cunning, as well.
