Ah fuck. You just reminded me that last night I dreamed the next episode was out. In the dream I was aware that Legs From Here to Homeworld was the latest, but didnt question why the episode was set in the temple bubble room. I only remember from a certain point, but Ruby and Sapphire were bubbled and Steven popped them, but they fell to the ground and cracked. Hurriedly, Steven licked them and pressed them together and as they healed they merged into one gem and reformed as Garnet but with a single gem.
I know it was after Legs because Peridot was there too and in the dream I was disappointed that she didnt have a new design
