Sorry, this answer isn't as detailed as I had intended it to be ! Also if you decide you want to do a follow up, you don't have to answer this or any question directly ! I just came up with it on the spot
"My mother did what?" He asked, raising an eyebrow. And like that Skinner was caught in a white lie as he spoke to another person. And in the grand scheme of things, one that didn't even matter, some trivial detail over what she had at a party they may have mutually attended. There was no way of knowing that she in fact didn't like onions and wouldn't at that, not unless you were really close to her. But there was very little people to get caught by that would be more embarrassing than the woman's son.
The other person left before things could become...more awkward. Leaving the two together. Skinner started to explain, but half way through the younger man abruptly put a hand up. "It doesn't matter. That's not actually why I wanted to talk to you."
There was a short pause, mainly so that Etienne could take a sip of water. They may have been at a convention but that didn't he really got a lot of talking in. He had heard of Skinner as a trainer, and like many people by now, found his unique choice of pokemon to be interesting.
"Your yanmega, how do you keep it from causing unnecessary extra damage when battling competitively? I don't see a lot of trainers with them, not with the shockwaves they produce."
For Etienne, the big easy lie about his true position is fine for forum game purposes, though canonly its a well guarded ! If you want a lie that's easier to catch, you can ask about his relationship with his mom. As nice as his position at SAXA is, its still probably strange to see anyone give up working with a famous and well funded scientist.
Or smaller lies like being happy to see you or eager to help or etc also work. He's not. He probably doesn't like you
