* The prison level in the Xbox version of ''Double Agent''. Where in the hell does Jamie Washington get a combat knife in a prison to give to Sam?
** [[CaptainObvious He smuggles one in.]]
** [[FridgeLogic How exactly?]] [[AssShove In his ass?]]
** Other contacts in the prison? Stole one off a guard?
*** Ask the criminals in RealLife who have smuggled worse into prisons.
*** This. There have been inmates who have smuggled ''handguns'' into prison and kept them hidden from guards.
*** Inmates have intimidated, persuaded, and paid guards to bring things into prison for them. There's a reason money is contraband in prisons.
* Some of the "high-value target" retrieval bonus objectives in ''Blacklist'' don't make any sense. Specifically, the [=HVTs=] in the Qods Force HQ in Tehran and the one in the Airstrip in Mexico. While all the other [=HVTs=] can plausibly be expected to be recovered because they are either found in America or in places where friendly authorities are operating, in both of these locations, there are no assets nearby to retrieve the HVT. Sam and Briggs are the only Americans operating in Tehran during that mission and they certainly didn't bring the HVT with them in their van, and the attack on the airstrip was something that caught the team completely by surprise, and they were in much more of a hurry to escape since they were on an unauthorized mission. Yet in both instances, after you bag & tag the target, you still get the "retrieval is on its way" message for them.
** The CIA may have some undercover agents in Tehran that could do the retrieval. How they are able to sneak into the HQ of the Quds Force while they are on high alert and drag out an unconscious guard before his friend find him is another question.
* Although this got averted by the time of ''Conviction'' and ''Blacklist'', how exactly does Sam keep getting lucky enough to find enemies to interrogate that speak perfect English in the early games? Somehow I doubt a low-class, random Indonesian militant or a North Korean soldier stationed in some backwater base is going to know enough English to respond to Sam's inquiries.
** There are only three Indonesians Sam interrogates: One of Sadonoís officers at the embassy, a technician in the submarine base and Sadono himself. Itís not a big stretch to find three English speaking people in a large guerrilla army with several hundred members.
*** This. These are the only interrogations you ''need'' to do - everything else is essentially non-canon.
*** It's also very possible some TranslationConvention is going on, where Sam uses some of the native language where necessary.
* So the Blacklist attacks: American Consumption = contaminating water. Okay. American Fuel = an attack on a tanker full of fuel. Fine. American Blood = an attack on the American top brass hiding in a secret bunker. These all make sense. But what does putting nerve gas on a bunch of trains have to do with American Freedom?
** Freedom of travel and gathering maybe ?? Those are kinda cornerstones of American society and social model of life.
** It has nothing to do with trains and everything to do with the setting: The attack takes place in ''Philadelphia'' - a city symbolic of American liberty and law.
* So the ending of ''Blacklist'' doesn't make much sense to me. Sadiq claims that if he's killed the twelve nations supporting him will launch open war against the United States so Fisher opts to instead secretly imprison him. But President Caldwell announced on national television that U.S. intelligence killed him...so aren't these twelve backer nations gonna 'rise up'?
** Two possibilities: One, Sadiq is just speaking hyperbole. Given he's already a colossal failure with his terrorist plans, it's very likely his backers will disavow all knowledge of his activities. Two, the various nations are informed of his imprisonment even as the general public is left to consider him dead.
* Anyone think President Caldwell suffers from massive AesopAmnesia? She was nearly killed in an attempted coup perpetrated by a covert U.S. intelligence agency that had grown so out of control that it had virtually no government oversight. Then, bam! Terrorist attack and her response is to...create a covert U.S. intelligence agency with virtually no oversight that nearly causes a war with Iran. Sure the people in Fourth Echelon are good people but didn't 3E start out that way? What's to prevent another Tom Reed, especially if Megiddo is still out there?
** It seems likely she has a "Fight Fire With Fire" attitude regarding things. Given how she nearly was taken down by Megiddo and Third Echelon, she may think having such an agency directly loyal to her may be the only way to protect herself.
** Well, the people running Fourth Echelon are the ones who directly saved her from Third Echelon, including a disavowed operative and a double agent. It may also be that there are no plans to expand 4E beyond its current resources, keeping it from ever mounting an operation on the same scale as Reed's takeover.
* How could Grímsdóttir, who was born in 1974, and therefore 7 to 15 during the Reagan administration, not know the phrase "win one for the Gipper"?
* Was aborting the launched missile in the Chaos Theory level Battery really necessary? Surely one anti-ship missile couldn't hope to make it past the combined CIWS fire of the U.S.S. Ronald Reagan and its escorts (and that's if none of the Reagan's aircraft shot it down).
** The USS ''Walsh'' just got taken out by the same type of missile that got past its defenses. There was no way to tell if the ''Reagan'' or her escorts was going to get hit with an information warfare attack, so the safest course of action would be to have Sam take it out. He's right in the battery, why not put him to good use.
*** Given that the Reagan was laid down in 1998, and that the CIWS and ECM systems it employs predate the internet by decades, it seems highly unlikely that they could be remotely disabled, especially given that Grímsdóttir says "Even if it gets past the Reagan's Phalanx..." after Sam aborts the missile.
*** HollywoodHacking? This is [[EverythingIsOnline Splinter Cell]] we're talking about.
* In ''Conviction'', why did Grim send Sam after the EMP that would have endangered Sarah's location if she was just gonna have Vic Coste pick up Sarah in a chopper that could have flown her out of danger? Why not send him after the one that would hit the White House?
** Possibly, she was doubling down since either Vic or Sam could have failed. Alternatively, she might have planned on letting the White House get captured?
* The first novel has real-life weapons designer [[https://en.wikipedia.org/wiki/Gerald_Bull Gerald Bull]] as a PosthumousCharacter and includes details about his assassination and work that show the author did research-- so why is his name misspelled as "Gerard" every time it appears?
