The boat is depicted in the second mural that Dirk discovers in "This Is Not Miami". If the Boy always had the power to bring his fantasies to life, then presumably he dreamed up the boat also. It's possible that he'd lived in yet another place - maybe whatever preceded Wendimoor's history, maybe a third reality, or maybe just a glum children's home on Earth - and started to fantasize about traveling by boat to a new home where he'd have a family. By chance, the closest potential match to the "new home" he was imagining was in Montana, far from any sizable bodies of water, so the boat had to drop out of the sky to bring him there.
Remember the boat's name — "Male Infant, Pollock, Adrian". That's exactly what might have been written on a crib in a hospital back in the 60s. So the boat was Adrian's crib, somehow transfigured and transported. He probably had a dream about going on a voyage through the sky, and accidentally flew himself to Montana.
"Three Questions, One Answer"
The scene where Todd and Dirk find the wall of screens, the screens all swap to numbers. Dirk immediately goes for "3" and "1", citing the Arc Words "three questions, one answer" as his reason. Todd wonders allowed how Dirk could possibly have known this and Dirk acts all shady about it, because there's absolutely no way he could've known, right? It's a totally inexplicable piece of insight....Except it's not; "3?1!" was on the envelope that Patrick Spring left for Farah. Dirk had a perfectly reasonable explanation for thinking that'd work. So why didn't he suggest that to Todd?
The only reason why Dirk knew how to decipher "3?1!" on the envelope in the first place was because he'd told it to himself via the time loop, so anything going down that line of questioning about would have ended up at the time loop, which Dirk wanted to avoid.
Speaking of the screens, what was up with the rest of the symbols? We never got to find out what the rest of them were for. Especially the out of place symbols such as the 3D heart (the one with two colours, red and blue), and the glitching 21 number. An even better question: Why set up the wall of screens in that specific way? Obviously, connecting different symbols will give one a different result, but it's still very weird. Yes, even compared to most of the things in this show.
Bart's revolver trick appears to be Beyond the Impossible. To start, three rounds are fired in succession by the biker, followed by three misfired rounds. Bart recovers the gun, then opens the cylinder, possible rotating it some, but not removing or reloading rounds. She then proceeds to repeatedly pull the trigger causing, in turn, nothing, a discharge, nothing again, another discharge, nothing again, and a sixth and final discharge. There is no way that combination of events occurs unless at least one of the first three casings spontaneously regenerated new bullets and charges.
That was probably the gun jamming, to demonstrate Bart's plot armor.
It's unfortunate, since though this is the most plausible answer (in that it's not completely, 100% impossible that a revolver action could malfunction, then resume proper function all on its own, then malfunction again, then fix itself again. All that is required is an unseen entity tinkering with the gun mechanism, unnoticed, in between each trigger pull) this is the only instance in the show where Bart's ability leaves the realm of Maybe Magic, Maybe Mundane and plunges headlong into direct, supernatural intervention. Also, it's likely this explanation can be disproved Doylisitically by anyone who goes back and watches in HD to see if the gun is loading every time Bart pulls the trigger. On the other hand, there is a non-zero chance Max Landis had a prop gun created to perform in exactly the above described method, the man is quite fond of his creations for the show.
Actually actually, that was the point of the headscratcher, and it absolutely has everything to do with possibility. It's not a question of whether there is supernatural stuff going on, that much is always clear. But what is happening in this case is the first, and to date only, point at which the Universe's intervention in Bart's actions ceases to be simply "things falling into place" and outright changing a system from one state (three bullets left in a gun) into something it wasn't only moments before (at least four bullets in the gun). Ironically, the in-universe magic subtracts from the out-of-universe magic, reducing Bart from a Crazy Is CoolCoincidence Magnet to mere boring, Invincible Hero.
Considering Project Blackwing has a prisoner who dream up pocket dimensions , a shapeshifter who can basically become anything at all. Literally any object at any size with workable parts from a canon to a motor bike. Then it’s safe that the subjects at Project Blackwing are magic based. Bart literally killed thousands of soldiers on an open field. She walked straight into oncoming fire that missed. It is about possibility, however its not only about altering possibility in her favour but making the impossible outcomes, possible. In short her brand of magic that makes the one chance in a million, billion or trillion always the one chance that happens. Basically she is an invincible hero, as long as she follows the plan. The Universe will magically make her untouchable and a killing machine beyond what is probably possible. However the moment she deviates, attempts to use free will she stops being unstoppable and untouchable and made vulnerable. The only way to beat Bart is to make her question or doubt. Usually that was not the case but as seen with Ken and Suzie it’s possible.
It's perfectly possible, it just requires the revolver to malfunction in a very strange way, such that each trigger pull moves the cylinder *two* places rather than one. When the biker pulls the trigger six times, the hammer comes down on chambers one, three, and five (firing three bullets), then on chambers one, three, and five again. Bart grabs the revolver, spins the cylinder (which fixes the faulty action), and goes through chambers one to six, resulting in a discharge every second pull.
She accidentally didn't pull the trigger as hard as she wanted to.
A simpler mechanical explanation occurs: Since revolvers are fired by a hammer striking the firing pin, which in turn sets off the primer in the cartridge, one can speculate that the universe made sure to weaken the hammer spring when striking the even number rounds the first time, hence not setting off the primers. The second time around, the hammer struck normally and set the rounds off. In any case, it's clearly magic, but that would be how the magic was accomplished.
Dirk's unexplained knowledge
The Men of the Machine are first named in the recap narration. After that, Dirk knows their proper name and they finally say it aloud. Is that a minor plot hole or part of the weird universe stuff?
This is pretty explicitly explained: Dirk guessed. His entire recap of Patrick's life in episode 7 was entirely a guess. There were some facts he actually figured out, but everything else, he guessed. And Patrick Spring confirms that his guess was somehow correct. So yeah. Weird universe stuff. It's much like in the first book where he made educated guesses on the questions of an exam and wound up getting them completely, 100% correct.
This may be getting into Wild Mass Guessing territory: but what if he guessed that he was a fictional character?
