I don't think June will be back at the Waterford's for the birth - we've now seen the birth rituals, we don't need to see them twice. (it's that old tv trope of a groom practicing his vows before the wedding meaning that we won't see them in the actual wedding.)
I also wondered whether they put the Emily 'ceremony' rape scene at the beginning so that viewers would hear the warning for sexual violence and think that was it, and so be even more shocked and horrified by the second rape.
Definitely agree with those that have called it a rollercoaster of emotions. I also thought that Fred's 'treat' was a naive guilt type thing, and that he wouldn't realise how fucking hard it would be for June to have to lose her child again. But by the time the credits rolled I'm totally flipped to 'Fred planned it all'. No idea what his long term plan is, does he have any interest in the baby at all? Not even as a status symbol, or a means of keeping Selena placated? Or has his fragile male ego been so damaged by the threat of it not being his baby that he's seeking revenge and is unable to see all of the benefits a baby could bring him?
