Hey hey and thank you for the kind words first of all. Also just as a warning to others, further on in the post I'll be mentioning some spoilers. But should be beyond the fold-out cutoff.
And yeah, I'm glad the lizard's got his appreciators :D I feel like he's very much the character you either love or he annoys you to death. Which is fine, he's written like that for a reason after all and we wouldn't want Jules to be any other way.
And yeah, I can see why you might feel a disconnect in that scene, though do keep in mind that your mindset and that of James in that moment is likely quite different after what he had to deal with in the days prior. For as much as we try to have him reflect the player, in some situations there are just cisrcumstances that are difficult to induce in a player. Such as that grinding down of James over the last couple of days at that point.
Then as for the unlocks. You don't have Julian's last one? But that is the scene you just talked about...? If you played that one then you should have it unlocked.
Sam is the same Bioluminescence scene, just with you being closer to Sam.
As for the Nomax one, it's easily the trickiest one to get in the game. So no surprise there: You have to basically pursue both Nomax and Julian. Skip your first day of work to spend time with Nomax and make sure to bed him. Later, make sure to win the dice game with Julian and Wolf, and ask Jules for an "anatomy lesson". During the following scene, when Julian asks if he could spend time with Nomax, give him your blessing. Later, choose to leave Conway instead of trying to talk Arthur into letting you stay, and then go spend time with Nomax. You'll find that he and Jules were getting acquainted and get to join in.
