This is a fantastic episode, with one of my favourite Knightmare demises.
Finally, the first appearance of Mogdred. 

  He certainly gave them the hurry-up.
This team were generally good at directing their dungeoneer, but where was he going on the mills of doom?
Those cavernwights were after him like a shot a the start of level 3. 

  Cavernwights don't usually show such a turn of pace. They did well, not only to escape, but to actually reach the right hand door.
Ultimately, like team 6 in the previous series, they were undone by a single mistake in the level 3 clue room. But that's level 3, it has to be unforgiving.... They seemed to have done their homework (and studied the previous series) coz they picked Joshua's fabled horn, before choosing their other item. Sadly they went for the gem rather than the magic shield. (Altho a shield is not a weapon, they may have erroneously thought that, like weapons, it was of no use to the unsighted dungeoneer.)
They may have narrowly missed out on glory of being the first ever Knightmare winners, but still achieved a certain fame with their demise at the gaze of the medusa. It was a great touch that the 3 advisors were all turned to stone as well.
Their entire quest was well paced, just 30 minutes, even tho they almost reached the end of level 3. That would be unimaginable in later years....
Spoiler alert: By the time future teams reach the medusa's chamber, somebody has mysteriously removed the Christopher statue....
