Marshall noted that CIA paid him very well, though less than one million dollars a year.

Why would Sloane put his entire collection of Rambaldi serum out in the open where it could potentially be compromised? It's been established that Sloane is not dumb and well versed in Game theory. Even a novice in Game theory or contingencies would keep something that valuable in a spot that isn't easily reached or at the very least, easily compromised/broken, yet Nadia is able to destroy them quickly and conveniently.

If the passenger was already known to the russians, and they did experiments on her with the Rambaldi serum, why did everyone go through the trouble of collecting the Rambaldi artifacts to build "Il Dire", that's the final machine that gave Sloane the word "Peace" and generated the genetic code in "Unveiled". Also, some of the artifacts used to build "Il Dire" where hidden and untouched for may years so how did the russians know who the passenger was and what she represented?

Goof: When Vaughn, Sydney and Katya are driving away from the checkpoint outside of Novgorod 12, you can clearly see palm trees in the background. No species of palm tree grows in Russia.

How does Vaughn know there was acid in the beaker? He just picks up a glass rod and dips it in the acid, then puts it on Suit & Glasses. But the beaker is unmarked, and they didn't have a chance to see S&G use the acid.

Going into someone's safehouse and putting your fingerprints all over their secret cache of untraceable weapons isn't really a good idea. If Jack were to use one of those weapons donw the road to kill someone, then Vaughn's fingerprints would be on them.

Why did they give Toni a gun for the break-in mission? Given she's a prisoner out on parole and all, and she really only needs to get in to deactivate the security system, arming her seems like a real dumb idea.

Why did Sloane let Lauren and Sark get anywhere close to his secret Japanese base with a rocket launcher?!? Didn't he bother to search their vehicle? All they had to do was fire at his house as they were leaving, once they had the Rimbaldi info. Sloane didn't anticipate something like that?

We learn in this episode that Irina gave birth to Nadia after faking her death. Irina "died" when Sydney was six and was pregnat with Nadia (Sloane's kid) then. So why does Slone believe Sydney is his child if evidently she was 5 or 6 when the affair took place?

At the end when Vaughn is in Jacks Weapon-Champer he looks through a sniper-rifle with Scope. But he only opened the rear of the Scope and forgot the front. No wonder he always misses Lauren.

According to Brill, Bill Vaughn was killed by Irina after he rescued Nadia from the custody of the KGB. But now Katya says that Nadia was born after Irina faked her death, which means that Irina would have had to kill Bill Vaughn after she was supposedly dead; but all Jack, Devlin, and the various other CIA senior officers knew that Irina killed Bill Vaughn, so wouldn't they also have known that Irina was still alive? Of course, either Brill or Katya could be lying.
