Anastasia. My name is Anastasia.

And you needn't worry. We will return to our true forms in time. As I said, this has happened before.

[Sirens are tricky business. She's encountered similar on her own world. But here, she doesn't know how they will effect her if she hears them sing. She can always mute the phone if she's fast enough.]

I'll see to it that I'm not swayed by a Siren's call. Perhaps I can find a way to counter it? Also, how may I address you, Sir?
