It's too risky to use any of their blasting powers so close to the prism, for fear that the might break it, so instead of doing that the two mirror Stevens jump Lapis a the same time. Their arms grow like vines, wrapping around her as they mostly try to use their strength to force her back out of the tree trunk.

The prism Steven is trapped in floats right in front of her, even as the two reflections put their all into trying to shove her back.

Inside, Steven can't hear any of this. He's been left alone and afraid ever since Lilith imprisoned them, and the only changes he's felt is every time energy is trained from him, and split out into another reflection. He doesn't understand what it is, but he can feel himself dying.

As the fourth Steven emerges, his feels himself lose his grip. He falls limp, everything fading out.
