Now that you mention it, there are a few "reveals" or hints throughout the game that have not yet been resolved, so it is entirely possible that the pregnancy one will be, too. There are times when the MC is in narrator mode, such as when he tells us that if he had known why Bella was crying that night (when he kissed her in the library), etc., and at the end of episode 8 he says something like "but I'm getting ahead of myself." Hard to say if the pregnancy is present or future as a result. If future, it could apply to any of our love interests...
