Back at home...

"Yuna,
may I ask you something?
It's alright if you don't want to answer."

Just by the question alone,
Yuna knows that the question Elze will ask will be difficult.

"I'll determine the sensitivity of the question before I answer."

Elze simply nods her head and asks,

"Where did you get those scars from?"

Elze was referring to the scars on Yuna's body.

"You want to know where I got these scars?"

Yuna's hands instinctively moved to one of them on her body.
