Between the confusion of having multiple opponents grabbing its mushrooms or attacking it, and the distraction of that nice, juicy berry left behind, the wild Paras is at the very least slowed down in its pursuit. Sion and his Sneasel gladly take advantage of the opportunity to make a break for it, and he doesn't stop until they're a fair distance and out of sight of any potential pursuit.

Which, given that they're outrunning a disoriented Paras and a stunned Pichu, probably isn't that far, but still. While not on Ryner's level of ability Sion's still tried to keep himself up to par over the years, but hopefully Romelle won't be too winded when he does call for a stop and pauses to look and see whether anything's still following them...
