It'll be needed on a rewatch, it just doesn't exactly fit in smoothly on a live viewing. Like just look at the last few episodes> Reunited
Do I even need to explain this one?> Legs from Here to Homeworld
The first peaceful talks between both factions, Centi is revealed, White Diamond name drop, Leg ship is revealed, Homeworld is shown to be broken in half, White Pearl and WHITE DIAMOND HERSELF> Familiar
Slightly slower, but lots of lore tidbits and deeper interactions with both Diamonds plus a big song reflecting a major parallel> Together Alone
Interactions with the Pearls, more stuff with Yellow and Blue, TONS of new gems and the ball itself. Major dramatic turn
Then we get Escapism and it's cool and it's calm and yeah it's kinda boring but it works to balance things out and THEN we get the 44 minute finale.
