I thought it was a good episode, and the episode I think does hold importance for the future. A few notable things:
01.) Firstly, Steven's human family outside of Greg is introduced. We meet Andy, but it's also established that Steven has an Aunt, and Steven's grandfather is still alive living on an island somewhere. We'll most certainly be meeting them later, and I feel Andy will appear more than just a one-off.
02.) We get our new pet mascot character in the living Pumpkin, who I also don't doubt we'll be seeing more of.
03.) This is the second episode in the whole series that all of the gems and almost all main cast are in a single episode together, IE Steven, Garnet, Amethyst, Pearl, Lapis, Peridot, and Greg. The only 'main' character really missing in this episode was Connie (and depending how you look at it, Jasper). But as the series deep down is really a series about its characters and the different types of relationships that we all have, this I think is notable.
04.) Various smaller things I feel will probably play a role in the future. We now know Steven's family name (that's not Universe), Lapis and Peridot have a farm now, and I feel the fact that Andy has a plane and is a pilot isn't just a quirky character trait but may be used in the future.
05.) ...I thought some of the jokes in the episode were hilarious, and the message of the episode was quite timely.
