Was he frightening her or was a stutter natural for the girl? "Kalos! Our region are sisters, aren't they?" He's not very good at geography, but even then he should know that much. John return the stare back at Gengar. It can sense the other Pokémon's wariness, and the orange beast habitually glare down at the other one. Yes, his trainer may be a *Little* Goofy, but he's a good guy nonetheless! Leon could've probably tell how the Gengar felt if he minded it, but instead he tries to invoke a feeling of trust by smiling at it. "You're not trespassing at all! This place is sketchy so I'm just going to tell you to be careful. Since you decided to look around, did you find any lost treasure?" He was starting to sound like a kid, curiousity also taking over him.

That's when footsteps could be heard in the dark distance of the cave. It echoed as the couple of feet got nearer to where the small group stood. Leon turns to this sound, but he showed no alarm. Rather, expecting something to emerge from the dark.

The young female returned the smile of Leon with her own as she shook her head at the Champion's question "I didn't find anything."
Aurore felt a little bit comfortable talking to Leon, he seemed like a nice person as she tried her best not to be a bother with her weird self.
When she started to hear the footsteps she got in front of her Gengar to protect him in case some enemies or a pokemon were to come.

In his peripheral, he noticed Aurore standing guard of her Gengar and her lets out a light chuckle. "You don't have to worry," He reassures her. He's sure the ones approaching them aren't bad at all. In fact, they're his Pokémon! Inteleon and The Rock returned, smelling like soot and holding what the champion left behind: his snapback and cape. Throwing those on, would he look more recognizable? Even with his hair all frazzled up, that cape full of sponsors really fits him. "Thanks, you two!" He exclaimed to the new arrivals. To really make himself stand out, he does his ~~in~~famous Charizard pose. "That's right," He starts in a low voice, enjoying the build up. "I am Galar's *Champion*!" He hope that comes as a surprise. The more she reacts, the better. Leon loves that kind of attention. His Pokémon stare at Leon. Their expression is up to interpretation. Even though he can be quite outlandish, there was something with Leon's energy that awes people. That, or he's taken as a fool sometimes.

Her face reddened in embarassmen, how could she have not recognised the champion! She felt like a complete fool in front of a celebrity! She let out a small surprised gasp when everything came in place like a puzzle, even if she never met him or seen him all around Kalos people would talk about the Champion Leon from Galar and how cool he was with his charizard.

She quickly apologized. "I'M SO SORRY! I-i-i didn't recognise you a-and!..I-i completely look like a fool for not recognising the famous champion!" Her eyes were almost letting out tears from how ashamed she felt.
Beverly
He has mix feelings of her reaction. Partly bad for making her get so nervous as this, and partly of laughter from seeing how much she's freaking out. That explains what kind of person Leon can be. "Don't worry about it," He laughs a little with a shake of his head. "It's a little dark in here. I wouldn't expect anyone to recognize me instantly." Now that he thought about it, he didn't introduce himself as the *Champion* Before. It slipped his mind that some people might not know who he is. For someone who's full of himself, living in the spotlight, that's something he didn't expect. "If it makes you feel any better, I don't know who you are too! Well, except from your name Aurore Ballard." ... That sounded ruder than it should've been. His Pokémon notices this but they know it's this guy's own way of trying to make things better. 

On that note, Inteleon and The Rock decided to return to their Pokéballs, their work done. Leon thanks them before they disappeared. Without a word, he starts leaving Aurore's side. "It was nice meeting you." And nods. "I'm not going to bother you if you're busy spelunking." That was a joke and he winks at her lastly before striding off—and bumping into a wall. Now, Leon is smarter than this but it didn't help that the it's nearly dark. He almost can't see his hand in front of his face. Charizard was tuckered out from its early training of Gigantamaxing so the flame of its tail is a bit weak. After staring a moment bewildered at the wall as if it just materialized there, he turns back to look at Aurore. "You happen to know where the exit of this cave is?"
Michael
She calmed down herself slowly as he ressured her, she really tried her best to not make a fool of herself anymore from embarassment.
When he said that he didn't know anything about her she gave him a smile "I'm a ghost type gym leader in the kalos league!" 
He could kinda guess from her ghost pokemon but she didn't mind telling the champion after all she admired every champion and gym leader that she encountered.

Seeing that he was going and bumped into a wall, she quickly searched through her purple bag and took out a small light and gave it to him. "I might know where the exit is but i'm not so sure.." She said with a small bit of hesitancy as she tried to remember from where she came from.
