My theory: Steven and Amethyst are walking by Onion's house and see him with a wailing stone. They hear him talking with someone so Steven decides to hang out with him, when Onion walks away they find the wailing stone and hear Yellow Diamond talking and find out her plans and Onion walks in and fights Amethyst. That's just my theory.
