Ky miffs, uses his hands to straighten the uniform a little. It's just a way to do something, to exercise the fact that he still has control of his hands and doesn't need to get Sol's permission for that much, at least.

Ky's brain might be in one piece -- certainly is, even as war-influenced as his circumstances have been -- but that doesn't mean that he is exempt from needing other input in order to come to other conclusions than the ones that he has come to before. If he always knows what he's always known... The point is that Sol could clear things up, could with not very much effort make a rather big difference to how Ky thinks about things, so if he's doing them wrong Sol should let him know. That's just common sense.

"Curses often last until midnight, even for ones that don't last the whole day." It's not fairytale if it's what actually happens, and there's no reason for Sol not to acknowledge that Ky has greater experience with this, and tends to pay a lot more attention to what's going on over the network.
