An easy ride or not, there's something genuinely uplifting and oddly poignant about the moment they win. Treguard (and indeed Hugo) is clearly loving it and the team really do seem overjoyed, their smiles and relief incredibly infectious as HEROES is spellcast.
But then let's look at Level 3 - to win the quest they had to walk past some dodgy-looking cavernwights, tell a Gargoyle that he's awesome, say "No" to the massive scary face in the wall (probably the hardest thing of the whole level), cast a spell, cast another spell, and, erm...cast another spell from the F, R, E and E they'd picked up. With their almost complete lack of riddles or majorly difficult room puzzles, not too controversial to say that it was the easiest quest we've seen to date? They get away with it at least by being enormously watchable, their debate about what to say to Mogdred was genuinely quite compelling as was their near-argument when trying to get out of the dragon room :p From their first few rooms I can imagine Tim and co thinking that these guys are great and giving them an easy ride.
Especially as they blatantly stepped right off the edge of the stained glass room! No good cutting to the Magic Mirror as it happened, they were clearly let off there. Not saying they were guaranteed victory - even in that final room had they directed Mark to the "E" and forgot to tell him to stop they'd have had to have died, but things seemed certainly made pretty simple for them where certain other teams would have perished. Particularly when you look at the difficulty of Series 3 (maybe in response to this series?) I can imagine some losing teams finding it slightly unfair.
Well done all the same to them and their personalities at least made them a worthy winning team. It was all worth it to hear the cheap synth out-of-tune version of the KM theme that plays as they receive the Silver Spurs!
