Again, Nita is heard but- still wrong. He can smell the hurt on his human and she's not ok and he needs to get the last thing off him before he can go after the one that's appeared (then what, he doesn't know. Herd her somewhere she can rest and hide? that sounds a good idea.). It's annoying and the easiest way to make it stop is-

He opens his mouth and starts to Sing.

Between that, cartoon logic, and Siebren's hand on her shoulder, she's brought back to the here and now. As does meeting his gaze for all of two seconds because they don't know how to deal with this-

"Ears! Block your Ears!" She's already jamming fingers into ears as the air shimmers with purple energy. It's not even a directed Sing, more of a general one that emanates from the pokemon and lasts for five seconds. But that doesn't mean anyone who hears it isn't a risk of a sudden nap.
