Giving a curt nod of gratitude to the admin, the luxray relayed a simple message; 'T.H.A.N.K Y.O.U.'
Truthfully, tail-flashing was somewhat tedious and could really only be used to commune short messages, lest they sit for hours in a pitiful attempt to translate a simple 'No, no I do not have a trainer. Why would I be here if I had a trainer.' Unfortunately for his pride, he had to take all the help he could get. He may as well be diplomatic about it.
Truthfully, overseeing the trials was boring, and last time had ended with Tesla caught in a poorly aimed net, pinned against the wall by a grunt who had assumed he was one of the many Pokémon for stealing practice. To be fair, the grunt had excellent aim, but terrible perception.
As per usual, Tesla's thought was disrupted by an intrusion, ahem, polite interjection, of a team member into the conversation. It was an admin this time, who apparently found the trials mentally taxing as well. Especially the guarding one. Truthfully, no one liked it, but, of course, it was a nessicary requirement anyway.
Again his cognition was disrupted by a noibat, the grunt's this time, who had a nasty bruise from a grunt mistakenly trying to catch it. Giving a somewhat sympathetic sigh, Tesla nodded in the direction of the noibat, speaking to it in the language of Pokémon, "I feel your pain."
