Hearing Samantha speak fluent French and having an accent just like a native, Melissa was shocked and very embarrassed. She had insulted her awhile ago thinking that Samantha wouldn't understand anyway, so she spoke without care. Melissa lived in Country F for years but her accent has not improved. So having been told that she speaks like a Spanish cow, she took it as an insult. That's because it means that she was trying too hard to sound authentic in French accent and failed.
When Daniel heard Samantha, he had understood what happened. Melissa must have said something offensive to her. His brows furrowed as his expression turned dark when he glanced at the woman. He didn't even wanna talk to her, he felt that it was too much a waste of time.
"How did she offend you?", he asked.
"She couldn't, she was speaking gibberish. It was hard to understand. Doesn't matter, it's not important."
The woman was taken aback by what she's hearing, 'Gibberish? Not important?'
