Character mistake: Shaft meets Junior for the first time and mocks him with the offer of bubbly water. Junior says "And as for that wedge of lime, it makes it alkaline, so..." It wouldn't, since lime juice is rather acidic. (00:23:10)
Character mistake: After the shootout at the restaurant, Junior finds one of the perps' cell phone and calls Bennie, exposing her as the one who sent the killers. He even comments in front of Sasha "Got your ass" before telling his dad about it. Later outside the warehouse, Sasha comments "So Bennie is the one who put out of the hit on us at the restaurant." She should already be well aware of that. (01:14:15 - 01:23:20)
