Ever since we learned the episode title "Familiar", I guessed Lion or Lars would somehow be important (because they're basically Steven's familiars). That didn't happened, but we did see a bunch of other beings (re)created by Pink/Steven's powers. I'm not sure if that's a coincidence or a deliberate double meaning.
Finally got around to playing Save the Light. It's a pretty good expansion of the first one, and the core combat is really fun, but clearly unfinished: Though definitely improved since the initial release, it's still got some annoying bugs where characters get stuck mid-animation (the first time I got to the Final Boss, Steven fell through the floor) and it's there's some hilariously obvious cut content (like one or two bosses and Lapis as a party member).
When it comes to the matter of White Diamond, I'm still thinking she's like Father from FMA and created the chromatic diamonds by purging herself of her emotions to become "pure", and the fact that we saw some sort of life essence being extracted from the diamonds to presumably manufacture new gems with gives me an idea of what that process might have entailed.
My forecast for Together Alone is that at first it'll seem like Steven's approach is working; he makes some headway with Blue and/or Yellow, but then he runs into a brick wall with White Diamond, and does something that gets him locked up in his room (probably fusion), which brings us to Escapism.
We Hopaled for Opal and got the worst.
Also, the end of that Dream Sequence had me uneasy for the rest of the episode. I imagine that was their intention.
And RIP those two Gems. I think the captions called their Fusion "Jadeite", but I'm not entirely sure.
Jawbreakers on sale for 99¢Spoiler marks aren't really helpful more than a few posts after the first on the subject.
I love that the show itself agrees that Yellow Diamond is Lesser Dog, and that her neck makes her look like a rokurokubi.
People keep saying that they think Pink and White switched Pearls. Is it possible that Pink's original Pearl was just shattered? That seems like a simpler explanation.
Next week is "Escapism," then we get a week off, then it's the hour-long season finale that was initially conceived of as the series finale.

"that's just the Diamonds being weird and horrible and making living beings just to literally use them as walls and statues."
I got Castle Lemongrab flashbacks. Bits of Candy Kingdom too, especially when the pebbles came in.
Somebody please dub Yellow with Lemongrab's voice.
