Her side of this "dialogue" is told from her POV in a later LN volume. (This chapter is from LN volume 4, Ariel's POV is in volume 5.) What she says are:
“Hi there. I’m your grandma.”
“Sorry to ask this right off the bat, but could you stop attacking the queen now, please?”
“I see. I suppose I have no choice, then.”
“Well, that was a short-lived relationship. Good-bye.”
