> That is to say, everything that you are going to see in this episode are just excuses in order to put the divorce problem as an obscure theme that isn´t noticeable with a very casual eye. This is because everything shown serves as a filter where it can easily go unnoticed but at the same time, anyone has enough elements and little details to detect that said situation has occurred.

> These two little moments when Terramar greets his parents speak volumes because there is a subtle feel that both have been missing his presence at home and the divorce raises because of the fact of having two houses and that those places aren´t all that near and one has to spend a few minutes for rotating between them.
This moment is what made me really think about what you lay out here. 

I maybe about to retread but I'm going somewhere with it:
    Ocean Flow: Terramar! Welcome home, baby! No excuses. This time, you're staying for dinner.
    Terramar: [chuckles] Scootaloo, Sweetie Belle, Apple Bloom, this is my mom Ocean Flow. And this is—
    Ocean Flow: [gasps] Princess Twilight Sparkle! What an honor! You know, Silverstream just raves about you.
    Twilight Sparkle: Well, she is one of our most hardworking students. In fact, I brought this form for you to sign so that—
    Ocean Flow: Both my children are so smart. Would you like to see their baby pictures?
    Terramar: Mom!
    Twilight Sparkle: That sounds adorable! I'd love to! And you know, to find out about aquatic pony early development and, uh...
    Cutie Mark Crusaders: [giggling] Research.
    Ocean Flow: Oh, well, maybe your friends would like a snack while we're gone? Some kelp chips? Fish oil tea?
    Terramar: No, thanks, Mom. I'm gonna go show them around.
 It's really interesting to watch moments like this play out and to think of it from the child's point of view. 

On the one hand, I think it's masterful. Brilliant even to have this subtle moment like this, to have it inferred within the dialog so smoothly. It's pretty rare for media of this level to have it. Heck, media as a whole has moved away from the subtle even in the highest ranks of our arts and culture. From the shrill screams of moral messaging to smacking someone upside the head with existentialism this is perhaps a greater achievement than at first glace.  

I don't want to say MLP was brilliant A+ story telling all the time but stuff like this or even as far back as The Cutie Mark Chronicles do standout to me. Part of me wonder if I am just reading in to it but their really is a fair bit on could go into here, from divorce itself to observations of Seapony/Hippogriff culture. Though I have ultimately decided to go a different rout after a memory from my childhood brought forth something surprisingly relevant...

Another show dealt with this topic, and I'm going to compare the two.

> not because she doesn´t want to talk about the topic, but because of her character and the fact that she was eager to present other things in the meantime.
I actually do wonder if you could take her whisking Twilight away to look at Baby pictures as a way to avoid having it brought up in front of  Terramar.
