Tyler is normally very careful about the emotions he shows people.

He stares at the Golurk in open shock.

It takes him a few seconds to pull his Pokegear out so he can actually evaluate it, and gets back: "Golurk, the Automaton Pokemon. It flies across the sky at Mach speeds. Removing the seal on its chest makes its internal energy go out of control.."

As the little voice is still talking, he shows his Pokedex to Akane with an openly confused frown. Its typing is right there, babe.
