Considering how effective she's been at recognizing all kinds of symptoms and her general paranoia, I think Satsuki can rescue Sae from this one at least temporarily. What I'm wondering is how she'll address the mom, because based on how every other conversation she has goes I can't see anyone changing their mind unless she pulls something like what happened last chapter.
Also, wonder if the state of the guy who was in the car during the crash is going to get brought up again past the two times we saw it.
