Everybody loves Pearl, and this was a really good Pearl episode: there was so much emotion, it showed off Pearl’s qualities and her flaws so well, and she was reminded of how much she appreciates Steven.
Just in case Mirror Gem and Ocean Gem left any doubt about whether Gems were from space, Space Race definitely settled the question. That’s enough to give it some nice lore points (so thanks again to Pearl, this time for the exposition).
Finally, one more accolade for Pearl: she is a very good mechanic. So what if her ship couldn’t leave Earth? She built it in one day. Very impressive.
