Deliberate mistake: When Morpheus is facing the twins' car, the road's not all that wide, and there are concrete barriers both sides of him. After he rolls to the side and slices their car, we see a side shot, quite far back from the road, and the barrier closest to the camera has disappeared (presumably so we get a better view). In a closer view, both barriers are back again. (01:29:25)
Deliberate mistake: In the scene where Trinity jumps out the building with machine guns and an agent right behind her, we see that while they are exchanging bullets, her hair is slick back and wet. But once she is shot and falling down freely, her hair is dry and flying freely.
Deliberate mistake: In the scene where Neo is sitting with the oracle and talking, there is one quick shot of the fence area where Smith comes in. In spraypaint on the metal fence it has "ONE" written across it diagonally up to the right. When the oracle leaves and Agent Smith comes through the fence entrance the spraypainted "ONE" has disappeared.
Answer: Well, they get defeated. They probably weren't killed, as they reverted to Ghost form (and were still alive when they did it, as they were screaming) which would repair any damage they sustained, but i can't imagine them being willing to go back to the French guy, if he's as powerful as he's made out to be. They're probably just in hiding somewhere.
