Steven is too busy crumpling in on himself, at first, to really think of any kind of plan. The combination of trying to keep his bubble up and the emotional stress of everyone around him is making that really difficult (not least with Peridot basically yelling in his ear) and so Amethyst addressing him specifically is exactly what he needs to focus.

He knows what that gesture means. Right - right! Fusion! They can do that! That is totally something they've done before! Just remembering that combats his anxiety with a surge of lingering pride, and though it takes a few moments for her offer to process, gradually it sinks in and he blushes a little, nodding his head.

"Peridot - Lapis? You two gotta make sure the van makes it down okay. Amethyst and I have got this!" He reaches out to grab Amethyst's hand, filled with triumphant enthusiasm, before suddenly pulling back and remembering:

"But... we should probably get out of the van first." Smoky big.

Steven pushes open the door and tugs Amethyst along with him, immediately grinning and raising his own paw to initiate epic fusion high-five. The bubble with pop with an outward force that sends a shockwave through the water, and also knocks Tamatoa's grip loose for a few precious moments.

AND SUDDENLY, SMOKY QUARTZ IS THERE!

"Hey, hate to burst your bubble-" they quip, and immediately launches a yo-yo and Tamatoa's face.
