And by the way...
The kid that stole the dragon then got his eye cut out had kind of a moon face, round nose.
The older brother was tall and lanky with a pointy nose.
So what do they do? On the time jump re-cast, they use a tall lanky guy with a schnoz for grown up moon-face.
And a flat faced guy for the gown up pointy nose kid.
One is a lazy hedonist who got fat. The other is an angry, lean mean fighting machine.
I agree the casting change is weird but the new look befits each character.
