Continuity mistake: When Lin lifts the rocks around the house in the final scene, there are eleven of them. But in the last shot, there are only eight rocks.
Continuity mistake: General Iroh attacks a squadron of five combat planes belonging to Amon. He downs two immediately. One fires back and ascends. At this time, the face of the pilot is shown. The other two descend. Iroh follows and destroys them. At this time, the ascending plane drops bombs. Again the face of the pilot is shown, but the pilot is a completely different one. The first time, he has a taller face, thick eyebrows, a pair of round and brown-tinted goggles and no mustache. The second time, the face is rounder, the eyebrows are thinner, the goggles are rectangular and pale, and there is a mustache. (00:08:10)
Answer: We do not see what happens. Avatar shows rarely have people killed on screen, so either he got away and was never seen again, or just died right there. As Amon was outed as a bender, he would not go back for his old boss.
