When Double's Cyclone side got 'candy-ed' wouldn't it have been more logical to use Heat? melt the candy and at the same time deceive the enemy for a sneak attack. Bat+Metal Sonar thing was way to obvious
Phillip summons the element memories. It was phillip's arm that was messed up, so phillip couldn't use heat. With that said the bat thing was what they had to do OMG.
seriously, double needs some slots to hold the gaia memories in (like kiva and the fustles), then at least the 'other' half can access their partners memories
