[The apparent unwillingness to change reminds Slipstream of Starscream, someone she's in the habit of lecturing. So, the 'giving everyone lectures' question similarly strikes a nerve with her, or sensor node as the case may be.]

It's not concern! A bot doesn't have to feel anything to just voice an opinion!

[Her voice trails off, bitterness fading from her tone. Maybe it's 'giving Korra a break'. After all, 'work-in-progress' suggests growth.]

I suppose it might be efficient enough, in a way, to just say exactly what you want, and what you can offer in exchange. But, it's also a remarkably efficient way to give potential enemies information to use against you!

Here's some free advice: don't go telling bots about this potential 'metal bending' whatever it is, unless you know you can use it to defend yourself.

It's like saying to other organics you can 'bend flesh', which is less than the breaking a bot can do.
