I just went through the code, and I think that would only happen if you didn't proposition Marco during your afternoon hangout. Before releasing that update I had to very quickly combine some Marco stuff, and looks like I auto-assigned you a friendly relationship with Marco without having a ponder scene, due to not making a sexual move on him.
I believe there are some other spots like that where Marco should have been pondered that I cut out last minute, I know of at least one other. I already plan to add something back in for that, so I can definitely do it for this particular path.
I'm also going to be adding in a scene with Isaiah before the showers where you can talk about the night before.
You didn't get a choice of anyone else to think about because you didn't reach certain events with them, so the game set you as friendly or neutral.
Now, if you did proposition Marco, then something got messed up. Definitely let me know if you did, or if there were any other events that seemed significant enough that they should have been commented on!

Oh, okay, I just went back through the code again, and now I see where a scene is missing. He still wouldn't tell you about wanting to hook up after the party, that doesn't come up in all convos, but you should still get an opportunity to decide yourself how you feel about him. I'll make sure that gets added. Thanks for pointing it out!
