You should fuck her as soon as possible. 

'I do have a theory in my mind.'

Amaya muttered.

'What is it?'

Nux questioned curiously.

'From what I know, [Sense] works on 'Intent to hide'.

That means, if someone 'wants' to hide from you, the [Sense] will be activated and you will know where that someone is.

Ember, however, comes out as an exception.

She, for some reason, doesn't get detected by you [Sense].

Of course, I have thought of a possibility where just like Thyra, who talked about 'wanting to kill you' without any 'intent' and got away with it, there might be a chance where Ember did the same thing.

That means, she hid without the 'intent to hide', however, there are two problems with that.

First, hiding without 'intent of hiding' seems impossible. Thyra just spoke those words, she didn't take any action, Ember, however, was 'doing' that action, the possibility of her doing something like that without the 'intent' is nearly zero, especially when she doesn't know about your [Sense] ability.
