It takes her a moment to comprehend why, exactly, he's holding out his hand. She doesn't get it. But it clicks and it shows as she cautiously extends damp fingers to take Dean's hand lightly. That's what he wanted, right? For her to take his hand in hers? What a strange custom.

Clearly mermaids don't do handshakes. She doesn't move her hand, staring strangely at the pair. What was she supposed to do now? She's really not sure. If Dean's lucky, he might see some of her chest, at least what hasn't been covered with her long, dark hair.

"My name is Syrena."
