Yasur's post about Lloyd vs. Egalt's teaching methods little earlier reminded me of this, but I'm making a separate post since it's not really entirely related, and I'm probably restating a few of her points anyways:
The thing that had me grinding my teeth in Dragons Rising s2 was the fact that, like... Egalt wasn't actually wrong. I do think that Arin would have benefit a lot from going back to first fang and learning the basics! Egalt was just a MASSIVE ASSHOLE about it. Like I imagine the audience was meant to, I didn't really like Egalt too much until Wyldfyre gave a new perspective on his whole "wasting my time" shtick, but even before that I had to admit that he was actually right about that.
Of course, even if he HAD been nice about it, there's still a good chance that Arin still would have been to deep in the "everyone's relying on me" pit for it to do anything, but still. Worth a shot.
