When Omar is walking through the alley you can see him carrying a double barrel sawed-off shotgun under his coat.
However, when he is robbing the stash house minutes later he is using a pump action 12 gauge shotgun.
Omar has been limping severely, for several episodes now (since the "some Spider-man shit" jump), including the beginning of this episode. But when he walks into the corner-store where he meets Kennard, suddenly his limp is gone.
The tag on the body bag misspells 'decedent' as 'decendent'.
