[Osomatsu swims over hesitantly, looking like he's seen a ghost after having passed the wished-for knife off to his brother to vanquish the sea witch. He opens his mouth to speak, but seems to clam up for the moment and looks off to the side.]

...Now that I think about it...Osomatsu, Choromatsu says you gave him something with which to stop Totoko. Where did you get it from?

[The eldest mer continues to keep his mouth shut, mostly because he knows he'll choke up if he speaks and he refuses to in front of Choromatsu. But too much time passes, and he eventually chokes out-]

The...the goddess...u-up on the island. I wished for it...

[...and then Poseidon freezes.]

[And then is interrupted again by Osomatsu before he can say anything else, who is shouting at this point so he doesn't just. Cry about it.]

You gotta go up there, Dad! He's not okay!
