Fontaine/Atlas's Hidden Control Over Jack.
--- --- --- --- --- 
Ryan Pulled a 'Sherlock Holmes' :
To discover the links between Jolene - Culpepper - Tenenbaum - Fontaine - Suchong - Atlas - Jack
Ryan 'worked it out', and then 'took care of' some of them, and took precautions against others.
We have no conclusive evidence that several alleged murders were not really Fontaine "Cleaning up Witnesses" ( 'loose ends' ).
This all would make a nice MMORPG Flashback storyline.

The Jack WTF Project ( Retconned to the 'Ace In The Hole' - More like 'Betting on an Inside Straight' ) : 
Celestial navigation and flying a modern passenger airplane and crashing it without killing yourself (a good trick). All things you don't just simply inject into someone's brain. That takes real training which takes years to someone with an aptitude ( Perhaps holding the pilot and navigator at gunpoint ? ( Navigator required - They did not have GPS and had to use Radio Direction Finding to get to the coordinates which Jack would have to specify - handily that note was there, as Jack's 4-year-old talking abilities may have been limited. )
Oops, Jack effectively murdered everyone else on board, never mentioned Cuz it might interfere with the writer's 'plot', and their Player manipulations. ( Imagine the conditioning required for THAT atrocity ... ) (( We have the writers leading the clueless Player, who is ignorant of any/all possible things involved - having to believe everything they are told, and not even getting conflicting impressions to clue them in that things they are told are NOT all true. ))
Imagine what Fontaine coulda done with ALL the Resources and Efforts spent - The geometrically larger and larger extent of the whole WYK Project. ( DO most Players realize/understand what would be involved in it all, how preposterous it is ?? James Bond 007 Villain Plans 'To take over the World' are simpler.) Look at all that stupendous Effort/Resources that went into this mere "Backup Plan". Fontaine instead should have been putting all that huge effort into his Primary Plan ... ( or even some other second plan - BOTH which would be far simpler and FAR Less Risky/Failure-prone. Perhaps if he had, he might have succeeded ). 
I called it "The Inside Straight" when I heard those BaSx] writers came up with "Ace in the Hole". "Ace In The Hole" is usually used as part of the Primary/main WIN Plan in a hand of Poker, and not some tertiary 'backup plan'. I suppose it 'just sounded good' to the DLC writers.

List those Costs/Difficulties Here :
* 'GETTING' the embryo from 'Jasmine Jolene' (Ryan's Child) - How could that event even be 'planned' ??? This whole complicated plan was just created 'on the fly' ?? (( Maybe for game writers, things work that wayGames created 'on the fly' - And Levine's repeated rewrites of BioShock and Infinite turned out to be rather costly. ))
* Creating the process to rapidly grow an embryo/human ( Imagine all the mistakes/failures before it actually worked - hundreds of dispose failures, at various 'stages' ? ) 
* Tying up much valuable time of Suchong and Tenenbaum ( and other expensive personnel and lab facilities )
* A Conditioning system along with it's 'teaching data' - It is not JUST the machines, but all that stuff fed into Jack's brain has to be produced. ( Useful later for Little Sisters. Perhaps some techniques existing already for the Maintenance Cyborgs (Pre-Big-Daddies). This would include conditioning lessons for all the skills which Jack would be needing.
* Disposing of 'Loose ends' to maintain the secrecy. ( Could explain many of those Vague deaths/murders. )
* A 'Safe House' on the Surface -- More than an igloo in Iceland ( 'Jack' needed a stable/well-controlled place to be stashed for 2 years ).
* Trusted Handlers ( who cannot be too stupid ) who have to stay up there with Jack.
* Transport to and fro ( including training for Jack to get on a commercial plane flight without any 'complications' )
* The required Modern plane simulation training ( Someone ELSE's RECENT knowledge is required for Jack to guide and crash the plane without killing himself. 'Jet', doubly difficult ). Alternately : How to coerce the Pilot and Navigator to do the task.
---
Issues : 
* Liability of project security on The Surface (where Jack was stashed), AND in Rapture, for the entire WYK Project ( Fontaine can't have Ryan finding out ).
* So much had to be hidden/secret IN Rapture to carry out this project. 
* Why not just warehouse him IN Rapture ( so much possible to go wrong on The Surface, and all that needed to be done up there with all the various difficulties ).
* Seriously, feeding all that 'I'm a live person' background stuff into Jack was NOT really needed - Effort instead could have been applied to making Jack a more competent Assassin.
* Jack is a 'one off', and experimental. His conditioning potentially 'comes apart' at any point and the whole plan fails.
* People like Suchong KNOW about the Plan. This makes for some very plausible reasons about people involved being mysteriously killed ( Suchong, Jasmine Jolene, Culpepper, Tenenbaum, Johnny(??), etc ... )

WYK - Ryan Didn't Want to Tell Jack ( 'Give It Away' Earlier ) 
Perhaps Ryan was playing along so that Fontaine would fall into Ryan's trap. 
Ryan could have monitored most of what Atlas had said to Jack ( The Radio system is part of Rapture's infrastructure ).
The ante room to Ryan's Office at Rapture Central Control indicated that Ryan knew about 'WYK'. AND SO, he figured out about Fontaine still being alive ( as this 'Atlas' person didn't have the resources to setup such a thing ).
Suchong may have had a 'In Case of my Death' message left for Ryan ( He had much to fear from Fontaine, who might want to 'eliminate' various 'loose ends'. )
Simplest : The Gamemakers Had Their 'BIG PLOT TWIST' disclosures would have ruined. They already botched it by having it 2/3rds of the way through the game, rather at the End.

Humor - What if "Would You Kindly" had been ... :
:"Hey Asshole, Do what I say !!!" ( in an Irish Accent )
: " W T F " 
: Or "The Worms Told Me ..." ...
: "Boyo" ... ( Check to see if he said that every time too ... )
--- --- --- 
Ryan Figured It Out :
: Ryan has his WYK Stringboard, and had linked it all together.
: Atlas appearing after Fontaine 'dies', and is handing out Plasmids like Candy to his Terrorist minions
: Ryan hears the lies Atlas is telling Jack in BS1 ( tapping into the same radio Comm infrastructure )
: How does a common "Fisherman" run Jack as his pawn Assassin ( Only Fontaine had the resources to 'make' Jack).
: Did Suchong eventually 'Tip Off' Ryan about the WYK Project ? ( Suchong was a Survivor, and 'knew which side' his Staying Alive 'Bread was Buttered On'. )
If how moronic Atlas is in BaS is real : 'Atlas', supposedly incognito, while 'locked in a prison', acting 'the Big Man' amongst those Splicers, and also with some Fontaine thugs temporarily locked away there ( Who should NOT know the truth who Atlas was unless Fontaine really WAS that moronic ... ). That all with Ryan listening in to everything going on there -- and with Sullivan going over ALL of Fontaine's properties ( including Fontaine's Mall ) looking for evidence of all the crimes Fontaine had committed, and so turning up more pieces of the [WYK|[WYK puzzle]]. 
--- --- ---
 Would be neat for Ryan to say to Jack : "Would You Kindly Murder Everyone On The Plane" ... "Oh, Oops you already did that before you arrived in Rapture. My mistake."

The Whole Jack Gambit ( A Mutant Tyke Created to Murder Ryan ) - It ALL was like something written in your average online Fan Fiction
Overly complex, and with great cost and huge risk of failure. A strange 'Plan D' contingency, when there were far simpler things Fontaine could have done to achieve similar ends.
It really should have been a Plan to make sure that Fontaine could "Get Out Of Dodge", and that would have been a tiny fraction of the difficulty, cost, and risk of this whole over-complicated game-writer-contrived thing.
AND : Writers having Fontaine FORGET the WYK Control Phrase in BaSx (DLC) - THAT was simply absurd ( those writers thus turning the Fontaine character into an Utter Moron - It is DLC-itus ).
---
IDEA : Suchong Can Clone Humans Now :
* Making many is not much more difficult than making one ( infra-structure and methods already developed ).
* No need to get orphan children for more Sea Slug 'Slug Hosts'
* Cleaned Slate 'Humans' for other experimentation, or for making into Big Daddies
(( Wasn't this how the Clone Wars in Star Wars got started ???? ))

Sullivans String Board

Sullivan would constantly report to his Boss (Ryan), and no doubt the Big Investigation into Fontaine's Smuggling Operation would turn up more interesting Clues, which Ryan started to piece together.
