"...hello," she tries.

You know, when you pay close attention to it, the shade sounds weirdly like a quiet breathy adult in a Peanuts cartoon. 

Well, as long as she can get it to go on for a while Rete will chew on it.

It can be so prompted.

What does Rete eventually conclude it's saying?

It is reciting memorized bible passages, apparently.

...well, known-plaintext attacks are convenient for this specific purpose.

"Can I get a third one to triangulate? That should be enough thereafter."

"If you must."

This one is muttering things it's hearing other people say throughout the Birdcage.

"Okay. Rete can understand shadows in general going forward, thank you."

Nod.

"Your service is appreciated."

"Thank you," Lorica repeats. "Are there other things you would like it adjusted to do today?"

"No."

So is Lorica going back in the dark or can she work on her own shit now.

If she doesn't have anything left to ask she is going back in the dark.

Figures.

But she is, apparently, a Scout. Who can stay tucked away in one place while her agents do her work.

Rete's talking to Dragon.
