That was certainly an interesting episode, and definitely one for fans of anything to consider watching.
That new character Quibble Pants is a huge fan of the first few books, but despises the later ones so much that he refuses to acknowledge they even exist. In other words, he's like one of those Star Wars fans that hates the prequels, or one of those Star Trek fans that hates everything that came after the original series. I'm sure we're all familiar with those types of fans. (I bet even this show itself has quite a few of them as well.)
And then when he and Rainbow Dash get kidnapped, his snarky attitude led to quite a number funny moments. But by far my favorite part was this direct Indiana Jones reference:
"Are you crazy?! Don't go over him!"
"Go over him?! Are you crazy?!"
then after they go over the monster and escape
"You said go over him!"
"I said don't go over him!"
I'm honestly not sure what to expect for the rest of the season, but it's nice to see that I can still get some good entertainment out of these new episodes.
EDIT: Two things I forgot to mention. First, quite a shame that Twilight couldn't go to the convention due to her job requirements, which I'm sure a number of people can relate to this. Second, even though Quibble Pants now knows that Daring Do is real, he does not know that she and A. K. Yearling are actually the same pony (unlike Rainbow Dash and friends), so that probably might make him wonder how the hero and the author know each other and probably never realize the full truth.
