The Iron Bull...

[Even if the name isn't one, the tone is warm and greeting. The Iron Bull was picked by the Unseelie; he can see why they'd want him, but that explains why he hadn't seen him before now - in fact, many of the Unseelie do feel like many of theirs... he's got to listen more closely!

I don't know what it is... -- I only know, it's -- what she wants. And that it takes a piece of your voice, your words, makes them louder. Like a war horn, except -- the command is words, and the meaning is in the words, instead of only the sound.

There are many things she thinks she wants to use it for -- a-and you can't choose and then change with a war horn, call a command clearly when it could mean the opposite. But she will use it only once for a command, and other times for games, until her friends tell her to put it away...

[And then when the joke's refreshed, she will take it up again and use it to issue a new command.]
