You were a child of Ceto, the goddess of sea monsters.

So you were immune to Siren songs! As well as Charmspeak. A fun perk. But, the Argo II was attacked by sirens, a normal occurrence by now.

And everyone but Jason didn't bat an eye at you going outside, to the docks to get the monsters off. Jason just stared in confusion and worry.

When you came back in, Jason ran up to you, hugging you tightly.

"How- How didn't it affect you?! Are you okay?!" He panicked.
