Hahaha XD Silly Leli is silly :3 But yeah, I guess it's all opinion. When I was on the podcast I got people telling me I sounded both younger and older than they thought I would, so... *shrugs*

Ah, that makes sense. And lol, still, I'd expect you to remember at least some of the names XD XD XD

Yep, she dies. In the original, the witch turns her into a human and she can't speak or touch water. If she touches seawater she will die (so that she can't give up and try to return to the sea). The mermaid meets the Prince but the whole rescue thing never happened, so he doesn't have that memory of her like he does in the Disney version, rather, she's just been stalking him from the water. As such, she doesn't know that he's actually in love with another woman, but the Prince likes the look of her so he invites her to stay at the palace. Everyone goes on a boat cruise and during the cruise the Prince announces that he and his love are to be married. The mermaid tries to get him to look at her, but he's with this other chick, so she realises that she's stuffed. However, her sisters come to the rescue, giving the witch their hair in exchange for a knife. They throw the knife onto the boat and say that if the mermaid kills the Prince, she will get her fins back. The mermaid agrees, but that night she sees the Prince happily asleep with his lover and can't bring herself to kill him. Distraught, she dives overboard into the ocean, burning up and dying. I think she then becomes a part of the air fairies or something like that :/

That's how I remember it at least XD
