Some people might take issue to being ordered around by a stranger, but Rokuro has spent his entire lifetime in service to another. Obedience, while possibly not in his blood, is certainly habit. He would much rather take the advice of someone more experienced than waste valuable time and energy for the sake of independence.

"How can you tell?" A question, not a challenge. To Rokuro the trucks are reminiscent of armored beetles. Flipping them over may reveal a weakness, but upon simple observation he can't detect a chink in their metal shells.

Whilst waiting for an answer, he whips a spiral of water up into the air, and then straight down onto the front of the truck. Hard enough to warp the hood and create gaps at its corners, which allows the water to flood inside and drown the engine within seconds.
