firstly to think that duke is in a postion to be only shot in the back if you look closely you can see that he is standing slightly out from the doorway and turned to the right so that it will appear that the bullet has hit the side of the sub and bounced back and caught him is his right shoulder.
ethan a goof that you have missed is when duke is taken into his bunk he holds his right shoulder then promtly lays down onto that shoulder if you think about it if you were hit in that shoulder would you go laying down on it.
it is at this time that they rescue pop's little brother they dont tell you where he has disappeared to but in a slightly later scene he is laying in dukes bunk.
on a whole this is a good movie to watch it has its funny moments as well as its sad but on the whole a nice movie to watch.
hooroo smokey
