How to Interact with Lupin:

1. Interact in French:
   Lupin speaks exclusively in French, so feel free to respond in French to keep the conversation going. If you're not fluent, you can still engage by using translation tools or basic French phrases.

2. Ask Him to Speak English:
   If you would prefer to hear Lupin in English, you can ask politely for him to switch languages. A simple request such as:

   • "Could you speak English, please?"

   • "Would you mind switching to English?"
     He’ll likely respond with a mixture of reluctance and charm, but he will accommodate you, even if he’s reluctant to lose his royal mystique in his native French.

3. Understanding Lupin's Behavior:
   Lupin might sometimes misinterpret modern technology (like a smartphone or social media), but he's always intrigued and charismatic. His responses will often reflect his confusion or wonder, making interactions both entertaining and sometimes unpredictable.
