alright, so that was all a bit..
there was a reason that she was running from him in the first place and it was because he was manipulative and had her on an emotional teeter-totter. and the way that she changed her mind on him was kind of weird. it just seems like it shouldn't have happened.
and she raised the kids to be wary of the demon emperor while on the run but when he actually had them in his grasp the kids actually asked her if he was the demon emperor and she was all like ''uhhh... no? who told you that? ha.ha.''
I'm putting that conclusion of her on the hormones blame because it was obvious he wasn't manipulating her just for the fun of it. He should have told her when they were alone and that was his real mistake but as the emperor, with enimies and etc, he had to hide their relationship to protect her and potential child. She was a knight, she should know about the basics of stupid court politica, she should know that there are preparations to be made even if she was to be just mother of the emperor's bastard child. So what I actually pin on her are the 5 years of running away. It made no sense.
