Since this episode is canon, and we know that this episode takes place before The Return and Jailbreak (Garnet is in her debut form), it will likely explain how Steven summoned his shield, and a big one at that, in The Return. And in Jailbreak, Steven summoned his bubble just at the right time to save the gems. Think about it! UG always helps kids with their problems, so this episode will likely be about UG helping Steven summon his shield or bubble. In the first preview, UG is pointing a bazooka at Steven. In the next preview, it is implied that the rocket launched by the bazooka hit something and exploded (there is burnt sand and smoke where Steven stands) yet Steven is unharmed.

Or this episode will be about UG helping Steven get his kite out of a tree, I dunno. Steven's been summoning that bubble at all the right moments since Ocean Gem, but I think you could be right about the shield theory.
