Episode 2 explains a little bit more about why he agreed to do it, but there was a bit of a con involved, since the Ringmaster sold him on one thing and it clearly ended up being something else.
It is! And I have to say, I love Ash more and more each episode. There was something refreshing about the original Ashley Barton not being a typical selfless hero I have to admit, but this version of Ash, who is much closer to the typical hero, is pretty great, too.
