These arguments always seem to take off while I'm away at work.
For the record, I do not think that running away/avoiding was Alto's motivation for
everything. But I do believe that it was a significant factor in his decision making in the series.
I've actually struggled quite a bit with interpreting that scene involving Yasaburo in Episode 11. Alto's responses really
do feel a bit like he's playing a cliched "rebellious boy who ran away to become a pilot" role.
Question is, why? Does he just figure its the easiest way to get out of the situation? Is he instinctively prone to act? Perhaps he's been playing that part for a while already because its a role that gave him a chance to pursue the sky he loves so much?
