When you're with Kira in the barn before having sex, she'll ask you to comment on her hair. If you like it, she stays blond. If you prefer the darker color, she reverts to it. So I guess technically there are four variations? I can't think of any other variation of that ending though.
When you turned them off they're off. The only thing you'll always see are the tutorials at start and the comments after the bridge scene.
I think the point is just that she knows the bus doesn't run 24 hours anymore (or yet, depending ...)
The screens that you haven't seen are not skipping on default preferences. So if the game didn't pause with CTRL then you've already seen that screen (and it counts on end screen), but changing Kira's hair color doesn't causing that stop.
It's been a while but I think not picking someone counts as a missed opportunity with with them since it then won't display in the chapter summary that you told Chris that you liked that character. So if you're going for Cece, staying silent instead of picking her would count as a missed opportunity with her not the other way around. The only thing I think it actually changes with story/dialogue is a line regarding Lexi if it you choose her and it slightly alters a conversation later with Chris if you pick one person here and then end up choosing another later (I guess conversation doesn't happen if you stay silent here but never tried). Best result imo is to choose the one you're going for this playthrough if you know.
It's always Cece... First time playing with the mod enabled and it's not always the clearest what the result is from the options. Thank you!
By choosing someone you're avoiding a missed opportunity. Everyone else counts as a missed opportunity.
