(Spoilers up to ShB) So, what exactly DID our Urianger DO?

[MrThinker]

But I think the real reason Urianger ends up getting blamed for all this is because he was the one left holding the bag, so to speak. That and he actually got down on his knees and apologized for it, whereas the Exarch never really had the chance to. For some people, the admission of guilt is a bigger sin than actually doing something wrong, as absurd as it sounds.

But the Exarch did apologise, no? It's like the first thing he says after beating the Dying Gasp.
