Friday evening, after dinner:

'Can I come in?'

She startles a bit, and looks up.  Kyubey is sitting patiently just outside her window.

'Sure.'  She opens the window.  'Is everything okay?'

He hops in through the open window and alights on her bed.  'There's no emergency, don't worry.'

She sits down beside him.  'What's up?'

'I don't think Lianne trusts me.  Do you know why that is?'

She hesitates.

'...why do you say that?'

'It's an impression I've gotten.  She just doesn't always seem completely comfortable with me.  I don't always understand humans as well as you understand each other, so I'd like your take on why.'

She locks up for a moment.  If Kyubey's not trustworthy then she should be trying to cover for Lianne, but if he is then she should be helping him show it so they can work together fighting witches - if she helps him figure out why Lianne doesn't trust him will he be able to lie to her better?  If she's evasive will he be able to tell and decide she doesn't trust him either?  If he is trustworthy and she evades - but if he isn't and she comes clean - he can probably tell she's hesitating - she's no good at this - 

'I - sometimes you come across a bit cagey,' she says finally.  'I don't think you mean to be.  But - it can feel like you're withholding things, sometimes.'

'I answer the questions she asks me.'

'Yeah, but - you didn't tell us that magical girls die if they use up all their magic, which is a really important detail.  If I were pitching it to someone I'd mention that kind of thing up front, so they know what they're getting into.  When you don't mention things like that right away, it makes it seem like you don't want us to know.'

Maybe if she only gives him advice that amounts to "tell more of the truth" he won't be able to use it to lie to Lianne better.  Maybe.

'But how do you know what details people want to know if they don't ask?'

'Well... if you're asking them to do something for you, and they could get hurt, they should know about that.  People like to know if they're in danger, or whether doing something would put them in danger.'

'Do you always assume everything's safe unless someone warns you it's dangerous?'

'Well, no, but - it's different if the person you're talking to knows a specific way that it's dangerous.'

He looks down.  'I guess I'm not always as good at interacting with humans as you are at interacting with each other,' he says.  'I didn't mean to make her suspicious.  Is she mad at me?'

He sounds... actually pretty sad about it.  Maybe he is just bad at humans.

'I... wouldn't exactly say that.  She doesn't know whether to trust you.'

He looks up hopefully.  'But I can get her to trust me by telling her things she wants to know, without waiting for her to ask?'

'By being honest with her.  With us.  By - warning us about dangerous things you know about, even if we don't ask.'

'Okay,' he says, 'I think I understand.  I'll do the best I can at getting her to trust me.   ...The best I can might not be very good, though.  Like I said, I'm not exactly the best person in the world at interacting with humans.'

'...I can help you, sometimes, probably.'

'Thank you, Kaylee!'

She smiles.  Maybe Kyubey isn't so bad?

'...would it be all right if I pet you, or would that be too weird?'

'I don't mind.  I've never been pet before.'

'Aww.'  She scratches him behind the ears.

He purrs.
