Mayor of clown town

Some things never change

Their injuries weren't anything TOO insanely severe. The worst they had when Sun and Moon rescued them was a deep gash in need from stitches, a twisted ankle and some bruising (especially where their chains were)

Although Sun and Moon were horrified to see all their old scars plenty of which were caused by Y/N just surviving in the sea. But plenty of which were caused by brutal batterings from previous "Owners" trying to tame them as though they were a beast

As for their Psychological injuries those are a bit more complicated. Y/N was discovered to be a siren years ago so they've been sold, traded, "tamed", and "trained" countless times. They have an innate distrust of everyone they meet now, and have some pretty heavy trauma that continues to affect them. But they're trying to heal and move on.

Along the way they kind of recognized that just like there are good and bad sirens, some humans are good, and some are bad. It took a lot of help and kindness from some nicer people for them to learn how to trust again but they're certainly more wary than when they were younger. So they're extra cautious with Sun and Moon. Scared and debating whether they can truly trust the two or not. As for the how, when you're chained up like an animal left alone in a cage one has lots of time to think and introspect

As for their role on the ship they really don't do much at first, as Sun and Moon insist on their injuries healing first. But after that they're just slowly eased into general shipwork. Mostly like cleaning until they learn the more intricate jobs. They still remember a littke from their early years becoming a sailor but they're very rusty.

That is indeed the trouble! Truthfully they don't really communicate at all. Since they refuse to talk, they didn't even acknowledge when Sun and Moon talked to them until a little after their injuries healed. At one point they tried talking through sign (only to realize they only know mer sign and Sun and Moon couldn't possibly know it)

As far as human languages go they can speak a few fairly well (perks of being a siren) but they're pretty illiterate with anything other than Mermaid and Siren literature so Sun and Moon just kind of learn to read their body language and facial expressions

Well...

Sun and Moon weren't the only one with their eyes on that merchant ship that had Y/N

The big difference is Eclipse knew what Y/N was and that they were on board

He insists him and Y/N have met before but Y/N doesn't remember him
