[MrTurtleMan]

It's basically her way of flirting. We have been shown that she doesn't actually want anymore to petrified him.

When?

When?

Chapter 13, she was flustered when master offered to remove the blindfold and relieved that he had a spare, even if she put an act of being pouty.

Wouldn't she turns herself into stone by looking into the mirror though?

 

[wallsg]

I thought it was a common theme that medusas who look in the mirror can turn themselves to stone.

Wouldn't she turns herself into stone by looking into the mirror though?

No.

1. According to myth Medusa's curse causes others to turn to stone when they look directly into her eyes.
2. Perseus kills Medusa by using his polished shield as a mirror.

Based on these two items, most strongly #2, seeing a reflection would turn NO ONE into stone, let alone Medusa.
