Yeah this is a good point. The diamonds took their ship to get to Steven but we have no clue how long it takes to warp from homeworld to Earth. They kind of glossed over it, which is a bummer because if they set up a time in universe then it'd give more plausibility to Spinel getting those weapons in such a quick manner. >>110157556
I also agree it would've been nice if they showed Spinel finding out sooner. If she heard she died, then she could've been plotting revenge on the Earth the whole time. But when she finds out that she was alive and just ignoring her, that would've twisted her revenge to Steven and it would've kept the plot exactly the same but given her more build up. >>110163555
I like the fountain idea a lot. Would've made sense and given some consequence the story since Spinel kind of gets off Scott free (which is dumb, she should've at least stayed to help clean up). Plus, that being one of the last remnants of his mom would've made for a touching scene, albeit a bit bitter as he reflects on her leaving Spinel out to dry.
