Steven has a lot of friends in different places. There are the citizens of Beach City, who would surely come to his aid if asked. There are the corrupted gems, residing in bubbles in the temple, one of which Steven was able to tame. And there are the Watermelon Steven's, semi-sentient beings that live to serve the holder of the Rose Quartz gem. If Homeworld tries to invade Earth again, the Crystal Gems would be no match. But perhaps, Steven and his new friends could be enough to stand up to Homeworld's forces.
