Question: I don't understand why Persephone let one of the guard go, instead of killing both of them when they're saving the Key Maker. Wouldn't they have made a clean escape that way?

Answer: Persephone wants to really stick it to her husband, the Merovingian. By letting one of the guards go tell him she is assuring that he will find out what she did, but it will be too late to stop her.

Question: Neo seems to understand enough about bending the rules of the Matrix that he can take on 100 Smiths and walk away with no damage whatsoever. Why then does he bleed when taking on the Frenchman's goons?

Answer: Smith doesn't use any cutting weapons, whereas it is a blade that cuts him in the Cheatau. Remember, that sword was swung at full force, enough to cleanly chop off a person's hand, and Neo is only scratched.

Question: When Smith tries to infect Bane and then Neo, they don't seem to be in a lot of pain when Smith plunges his hand into them. (They look more startled than anything else. Also, we are shown that the rebels' digital selves can suffer pain, remember when Trinity got shot?) Wouldn't it hurt if someone pushed his fingers into them, breaking their breastbone/sternum?

Answer: It's not explained in the film but it looks like Smith doesn't physically punch through the sternum; since it is just a digital world his hand melds with the persons body when he punches, and then proceeds to infect. He can control the matrix in some aspects this way.
