(After Sydney walks away unharmed from the park)
Eric Weiss: (sweating) I just lost 30 pounds. I'm not kidding. (edit) (Sloane’s fully convinced that Sydney’s the mole)
Sloane: I need to send a communiqué to SD-4 office in Rome: attention Spinelli, put it through Server 5.
SD-6 Agent: Yes Sir.
Sloane: I’m ordering with Security Section full knowledge, the assassination of an SD-6 Agent. Method: close range hit, this Officer’s scheduled to make a dead drop at Denati Park tomorrow, that’s when the kill should take place.
SD-6 Agent: Yes Sir.
Sloane: The target’s name is Bristow... Sydney Bristow. (edit) Agent Dreyer: (to Sloane) Sydney Bristow’s the mole... if you don’t follow protocol on this, I’m going to The Alliance. (edit) Disguised Voice: (on the phone) You have questions about Kate Jones. How far are you willing to go, Mr. Tippin? I need to hear the words "I'm ready."
Will: Why? Why, could my life be in danger?
Disguised Voice: Say the words.
Will: Yeah, I'm in. I'm ready. (edit) Sloane: You have your answer regarding Sydney Bristow.
Dreyer: What are you protecting?
Sloane: Mr. Dreyer, I still believe we have a situation here at SD-6. I strongly suggest you keep looking for the mole and stop questioning every decision I make. (edit)

When Sydney is telling Vaughn what happened after she used the Satellite phone to contact CIA to ask for medical help for Dixon, she says that the helicopter took them to a hospital in Buenos Aires. But then thought about what would Sloane do when he found out about this betrayal to SD-6. And came out saying that she lied to Sloane telling him she drove Dixon all the way to the hospital. (edit) Goof:
After Sydney was shot, you can see has three bullets stuck in her vest, but later after climbing out of the pit and collapsing on the ground, her vest is clean. (edit) If Sydney's fall was stopped by her leg catching on the ladder, then the sudden catch from that height and speed would have done some damage to her leg (like her ankle, or calf, etc), but there is no telltale sign or even a reference that she's sustained such an injury. (edit) Goof:
Will takes two beer bottles out of the fridge when he is talking with Francie about half way through the episode. Both beer bottles are most definitely open. (edit) Goof:
In the scene in a patio where she is discussing her situation, each time the camera flashes back to her, a different ear is uncovered or neither ear is uncovered. First right ear, then left ear, then neither ear then right. (edit)

The title of this episode "Mea Culpa" means "my (own) fault" in Latin. A phrase which is said to admit one's mistakes. (edit)
