And we know now, that Viktor can't have a child (shouldn't the king have known as well?). Which makes Diana even more valuable for the royals. She's a direct descendant of the current king like Renard, while Viktor is just a cousin i.e. from a Sideline. In the succession both Sean and Diana should theoratically be above Viktor as #2 and #3. And since Viktor's not gonna have a child the family is in dire need of an offspring...

It's an interesting idea though, that Grimm-Babies kind of 'hide' themselves to protect their mother. Would be interesting to know, if a Wesen-fetus is undergoing some 'special stages' as well...
