"I don't think I have either." She didn't have a reason to, but at the mention of mothers, she goes extremely quiet. She has her reason for this and it was more because of the fact they are meant to make you feel better... Which...Rapunzel knowing bits that she does now knows that...Gothel never really did.

So it was an odd thing to know that mothers were in fact meant to make one feel better.

"I mean... A doctor could at least explain why you might always feel worse before getting better." She is just going to ignore the mother portion of it all because she honestly doesn't know what to say about that.
