Burgundy had boasted about her knowledge of the French language for years, peppering her speech with it frequently - and condescendingly - towards her rivals on and off the battlefield. When Cilan suggested she come along to a convention for connoisseurs being held in Kalos, she was caught off guard, but eager to show him up, so she accepted.

Arriving at the convention after an uneventful journey, they were immediately greeted by a native Kalosian. Burgundy, partly out of habit and partly out of nervousness, responded with "enchanté."
The Kalosian's face lit up. "Est-ce que vous parlez francais aussi? Alors, bienvenue à Kalos! Avez-vous ici depuis longtemps?"

Cilan looked blankly at Burgundy, awaiting a translation, but she was frozen to the spot. "E-excuse moi." She said, lamely excusing herself.
She ran out of the convention hall, her face visibly flushed.

Once outside, she chastised herself for ever thinking this was a good idea. What will Cilan think of me now? She thought to herself sadly. Just as quickly, she banished the thought. Who cares about Cilan. It's his damn fault for bringing me here. He wanted to embarrass me! If I get my hands on him…

Her thoughts were interrupted before she could get too incensed, however, by Cilan himself coming out to check on her.
"What do you want?" She snapped, crossing her arms defensively.
Calm as ever, he smiled gently at her, encouraging her to soften her expression ever-so-slightly.
"Nothing, I just felt a little crowded in there. I thought I'd come sit outside with you if that's OK."
She grunted, but indicated that she was fine with it.

They sat in silence for some time, Burgundy silently praying that Cilan wouldn't bring up the topic of the Kalosian man, but her prayers went unanswered.

"About that gentleman back in the hall," he began, as Burgundy gulped - anticipating some sort of gloating, no doubt.
Noticing her expression, he smiled at her once again, free of malice, to her surprise.
"I guess he must of been from a different part of Kalos. Didn't sound like any French I've ever heard."

She looked up to see him watching her nonchalantly, and inside she was extremely relieved.
Burgundy was even relaxed enough to smile back at him. "Yeah, I guess that was a different dialect or something. Maybe we'll just speak English for now."

She was completely oblivious to the figurative bone Cilan had thrown to her. But if she had noticed it, she would have realised that he didn't care at all about her lack of French skills. His only intention in inviting her in the first place was to spend time with her, and he got his wish.
