Analysing the Albert Mycroft scenes from chapter 4 because I think it's really effective
Unironically I think these scenes tell you quite a lot about both of their characters especially Albert given that it's one of his first chances to shine after the backstory chapters!
So first of all, it's important to know how they even got in this situation in the first place - an opium ring is spreading across England off the back of the dissolution of the East India company, where it is rumoured that opium trading routes were handed over to nobles and high-ranking navy individuals (it's also linked to the mafia, which this series mentions a few times but rarely actually handles). The military and the house of lords are refusing to move to take down the organisation (likely because some of them benefit from the ring), so a military friend brings up the attempt at creating a shadow organisation within the intelligence branch that doesn't need permission of the house to act and isn't swayed by political interests.
Albert's reaction is quite important here - that he'd heard there was simply "no money to fund it, so the project was tabled" and that "If I could get into that organisation, it'd surely be of use to William." It's clear that he's done great research, prioritising knowledge of the political and social spheres. He is aware of its potential as an asset to the plan (Albert is prioritising William specifically in this), and directly requests William to help him organise a plan that helps him into its ranks. Then they spend a whole month planning this out, sorting out all of the logistics before he even goes to meet anyone at the Intelligence division - he's confident in its success before they even strike the deal itself. They've rigged the board in their favour without anyone knowing they're even in the game.
So now for the meeting at the Intelligence branch itself with Mycroft. Now, he is not named as Mycroft, but he is revealed to be at the end of Volume 3. Mycroft's first words seem a bit clunky in exposition - "and what would an indian army official such as yourself want from an intelligence official such as myself this late in the evening?" - but it also acts as a reminder of their ranks. Titles (Mycroft also uses his 'lieutenant colonel title afterwards) and ranks are incredibly important in this era, and Mycroft knows that a man like Albert would only show up at this time if it was an urgent or important request, so he's reminding him of the nature of such an exchange; that he, as military intelligence has the upper hand, and that Albert, if he wants something, needs to convince him.
Albert decides to forgo the titles after calling Mycroft 'Chief' once - he notes Mycroft's signifiers and plays back in opposite. His demeanour is generally much more casual, deciding to deliver his request as coming here to "talk to myself out loud." Of course, Mycroft is listening, and Albert knows this, and his request begins as an explanation of the needs and logistics (benefits and funds, mostly) when founding a shadow organisation. Mycroft is painfully aware of such things, and Albert is making sure that he knows that he is equally aware of the necessities. It's as if he's not talking about his own thoughts, but as if he's reading Mycroft's mind.
The line that brings it all together is "I will take care of all this myself," which brings a close to the logistical talk and acts as where he enters as a player in the game. He's offering to ease the burden on Mycroft's end, without the need for him to do anything but employ Albert in his stead. Albert's bold request is coated in layer of interpretive subtlety, where he gives the illusion of a concerned bystander but it is still clear that at the end of the day all he wants is this deal. Instead of taking the route of gaining trust and then making a bold request, Albert proposes the deal straight off the bat - using the request (and eventual results) to gain his trust.
And arguably this impresses Mycroft. It's that "Will you now? You have my attention." that really sells the idea that this boldness intrigues him. That upon studying his demeanour, gauging his personality, he is pleasantly surprised by the methodism, and welcomes it. He makes the deal right there and then, and it's by no means a small price - if the operation succeeds, he'd be transferring Albert to the military intelligence branch and letting him run that shadow organisation. It makes sense, given he'd be partly funding it, but also feels out of left field to trust a man he'd just met with such power. But Albert has clearly fascinated and convinced him enough in only a few sentences. Yes, it is still contingent on the results, but to even make the deal is an equally bold move on Mycroft's move.
Let's talk body language. Albert is aware that Mycroft is observing his every move intently, trying to gauge what he wants and if he is trustworthy. Yet his first decision is to turn away from his desk and instead adjust some of the memorabilia on his shelves. You don't usually turn away from someone when making a deal, given the fact it usually seems untrustworthy, but it's what he does with his hands. It's hard to tell, but it could be as if he's perfecting the placement of the items on the shelf. This shows Mycroft something else - that Albert has great attention to detail and a penchant for organisation. That he's calculated and orderly, which is the kind of person you need for such a role. And then there's the bow, and the hand to his heart - an action that's often seen as a sign of sincerity. He's indicating his honesty in taking care of the situation, and he's showing respect for Mycroft similarly with the bow. It's an indicator that he's not a threat, but an ally. That's part of how Mycroft comes to trust him. But still, each move seems calculated to elicit such an association. Albert is still playing the game, Mycroft allows it.
And Mycroft gets something he can't argue with - efficient results. The complete dismantling of the opium ring in a single operation, clearly calculated to perfection. Mycroft noticed this, and even points it out ("Makes me wonder just how much of this you already had planned out"), because that's the kind of mind he needs to run his organisation. Albert's insistence that's it's "all just a coincidence" is not supposed to be a convincing bluff - it's a calculated deflection from questioning the mind behind the plan (William, mostly) and what his ulterior motives may be. And this line from Mycroft - "well played, Lieutenant Colonel." Acknowledging that he's won this round, he gets his prize. He gets to lead MI6, with Mycroft as his superior.
Because they both know they're playing each other in some way. This makes much more sense with the foresight of chapter 17 (Scandal of the British empire act 1) - where Mycroft is aware of the fact that Albert has some ulterior motives, and he is prepared to test his loyalty to the empire. And Albert is aware that he's being tested. It's quite similar here - Mycroft knows Albert needs this position for something he's unaware of, and Albert knows Mycroft can't refuse these kinds of results. I do believe him and William will have done research into Mycroft prior to their meeting, and they are aware what he prioritises going in. With what Albert says and does, they play into his interests and necessities, in some ways like William plays into Sherlock's interests. But they're not quite playing opposite; they have a common motive and work as allies, but neither is trying to take the other down, considering how they equally benefit from their partnership. They sort of take to studying and testing in a mutual fashion. Each to gauge where the other's loyalties lie, and if they are to be trusted.
[I have more things to talk about with them... my recent reread has got me thinking a lot more about some characters and themes. I wish more of their interactions got into the anime or in morimu it's really important for their characterisations. Hope this makes any sense! I find it hard to transfer my thoughts into words sometimes.]
