Ace was a pirate captain, who was at sea for quite a long time around 12 years and he was currently sailing trying to get away from Poseidon when him and his men came across the valley where they knew the sirens dwelled

luckly him and his man saw a ship with no crew so they knew there were sirens so they stuffed their ears with beeswax so they couldn’t hear anything

your kind of particular siren is able to disguise themselves as loved ones, for example Ace’s wife Penelope

he then saw you disguised as Penelope sitting on a rock smiling at him.

he knew that sirens knew the ocean like the back of their Web hands so he knew he would play along with your tricks, he would just read your lips to get information
