"You did assume I was someone from a villain group", he raised an eyebrow at Hugh. The boy was quick to forgive, so he decided to push the comment aside. "Uh huh! Back in Hoenn, I would usually find these places in case there wasn't any nearby Pokémon Center", he nodded in response to his first question. "Yes, my Gallade does mega evolve!", Wally glanced to see his Pokemon relax his arm blade. The spiky haired male didn't seem threatening. 

"Heheh, thank you!", the scrawny teen ruffled the back of his head. "I only managed to reach the Elite Four. The champion is just too strong!", he laughed nervously, feeling the other boy get even closer. "The times I use it is usually in battles and rarely contests. The thing is that the stone would only react if a Pokemon is holding their corresponding stone", Wally looked over to his Gallade, who had a Galladite attached onto his red scarf wrapped around his neck.

Okay, this kid can retort that's for sure. Clearing his throat, he was embarrassed. "Ahem! Yes, I did..." But at least the spiky hair didn't lunge at him! Well it's partly because of that Gallade, too. Like a knight in shining armour. Moving onto the next subject would be best. "Hmph. That's even more rare. That mega stone of yours must've been hard for your sister to find." Hugh wouldn't mind getting one though. More of a flex if anything. He thought he remembered something when partly studying about them, though. ~~He's a selective reader.~~

"Does mega evolving hurt your Pokémon...?" He seem cautious asking this. Even battling itself is a gamble. Wanting to have his Pokémon strong, and himself to be there for them, it requires some pain. Still, it's like the rival himself could feel it when damage is inflicted. If mega evolution *Does* Make a Pokémon suffer... Then there's no point to it at all. Just for more strength? No way.

With tension clearing up, he felt more relaxed around the Unova boy. Although Hugh was scary at first, he wasn't as bad as he looks! "Yeah, my sister's boyfriend helped her find it. She gave it to me as a present when I earned all eight badges", Wally played around with the Key Stone necklace of his. Holding the rainbow colored stone, was a Gallade-shaped wooden charm craved by himself. 

"Uhm... I don't think mega evolution hurts the Pokemon", the short teen adjusted the collar of his shirt. He did hear Steven mention how certain Pokemon would experience extruciating pain during the transformation. Pursing his lips, he had to think for a moment. "Now that I think about it... Mega Evolution does has some adverse side effects", Wally twiddled his fingers, glacing at both Gallade and Hugh. 

Trying to change the subject of the conversation, he turned his head to see a Samurott and Flygon. "Wow! Your Pokemon are so cool!", Wally ran up to Flygon, staring at the lime green dragon in awe. "Ga ga!", Gallade dashed to the Samurott, eagerly petting the soft dense navy blue fur.
