Its cause hes like an extreme worrywart. Like the bad kind of worry. Though i still think he should know and just get scolded if he tries to just lock her up in a toom for the next 7 months pff. But also i never got why they hid it from her at least she knows now.
Did I miss something is there a reason he can't know about it? Like she seems happy at the idea of it and he definitely wouldn't be upset so-?
