This is the sort of sense I think we should be talking!
Yeah, everyone always says you have to use porn logic, which says every female character is on the table, but I can't help looking at this game differently. There's a lot of work being put into the story, so many little interactions and little facial expressions that we'll happily talk about when it comes to any non-lewd scene.
That's the main reason I am yet to be convinced of some of the popular theories (including Sally and Elena) - I don't think they fit either the story or the theme of the game so far (meaning one or the other, not necessarily both). With these two examples, I know you can say some parts of the story are starting to fit around them as possibilities, but other parts are not, and for these two it's more the themes that would be a departure from what we've had so far.
Of course, despite that, I'd be pretty happy with any of the suggestions, I'm a simple man sometimes
