Spark pulled a face unsure exactly how to respond. She didn't exactly try to be shy, it was just a feeling she got being around ponies she didn't know to well. She'd already taken quite a leap talking to Sound considering they'd only met the previous evening...

"I... I don't know how..." She replied with a worried look, "But if you think I need to learn then I'll try my best"

Spark couldn't quite hide the reluctance in her voice. She knew that she would likely have to defend herself sometime but all the same... she had spent her life helping ponies not hurting them.

Her chain of thought was interrupted by the arrival of their meals. A bowl of soup filled with delicious looking, fresh vegetables was placed before each of them and sided with a plate of salad. Spark had to resist the sudden urge to squee at the sight suddenly realising just how hungry she was. She had no idea where the food came from and Cook refused to give up the secret and simply told her "paradise" hence the name. 

Not wanting to seem rude by eating during their conversation, Spark looked to Sound to see what he thought of the food and if he had anything else to say. They'd have to eat pretty fast, the caravan would be leaving soon and they had to eat and walk back to the meeting point.
