I actually liked that scene, even if it was a bit ham-fisted. I think the writers were trying to give Monroe an opportunity to go on one of his historical minutiae-based tangents (“nerdsplaining,” as The Wild Sow put it), which they haven't let him do in a while. And Rosalee completely realized that he was about to tell her a long-ass story, because it’s one of those things about him she finds cute, and he knew that she was just humoring him (take a note, Auggie’s dickhead dad) so it didn’t come off as mansplaining as much as one partner putting up with the other's idiosyncrasies.
I have to disagree. I feel that they did show that strife was already brewing, what with the mother being obsessed with taking 5,000 pictures a day, and not even coming to bed because she had to post them right! This! Minute! The father looked like he was completely over it. I don’t know, maybe I’ve just seen couples like that, where one of them was clearly way more into the idea of having kids than the other, and sometimes they even steamrolled the other person’s wishes to get their way. But of course you can’t make someone be happy, so it rarely works out. You would think that the kidnapping and return of their infant son would have brought them closer together, but it didn't. They fell right back into that old pattern. So I think the strife was already there. Now, in the real world, of course that doesn’t have to lead to a homicidal teenager. Plenty of people have kids who aren't that into it (or even hate it), or are obsessive helicopter parents, and the kids manage to turn out okay. But on this show, where magical stuff is quite real, I think they showed that El Cuegle was trying to prevent a tragedy that was definitely imminent, because he tried not to intervene before, and that didn’t work. He didn't have to EAT the baby to kill it (lots of more merciful, less disgusting methods), but I think the story about his one failure (and the fact that Hank and Nick found evidence to back it up) proved that he was doing what was necessary.
But where is she sleeping? Where is she pooping? Even hexenbiests gotta go sometimes, right? She had a cot at HW headquarters, so we know she sleeps sometimes! Hell, get a motel room and work through your transition there! I don’t know why, but this is bugging me more than the layout of Nick and Juliette’s house, with the guest room that apparently came and went at will. It just feels so lazy, like they didn't feel like working out where Juliette was going to be staying after they "wrapped up" the HW storyline. Trubel got hustled out of town, fine, and Juliette is ... creeping in the tunnels beneath Nick's loft all day and night, cold and damp and miserable and weird.
