What about 'You can go to the Academy next year'... 'But that's a whole other year!'... I think that kind of counts as mentioning it...
True. But they never actually call any of the Tie Fighter's an "academy pilot", and the criteria that Black Knight seems be using is that unless it's named on screen it doesn't count.
For example he says that the only astromech's that can be used are R2-D2, because no other astromech is named on screen. He makes it quite clear that any named squad that didn't get mentioned on screen is non-canon and can't be used. So I'm pointing out that based on that the Academy Pilot is non-canon as well.
Don't get me wrong, I think his idea is clearly misguided, and his criteria is completely screwed... I'm just pointing out that he's not being consistent.
