At first, she didn't know what Sara was apologizing for, so there was a little glance of confusion before she continue and it made sense.  Kate's mind worked rather quickly, so naturally she might have these moments of confusion, like she was trying to parse the whole before it was complete.  A harmless fault.  It came from processing too fast and jumping ahead of everyone else, mentally, before realizing the leap went too far and you have to go back.  Anyway...Kate shook her head, letting off a sad smile.

The more who thought of her kindly, the better.  Myra's eccentric behavior was not [i]easily[/i] engaged with.  It required patience, and some people would cave on arguments largely because she'd thought so thoroughly on something, almost obsessively, that you didn't have a chance to find any flaws.  Or to put it her way: 'If I'd seen any flaws IN my argument, I wouldn't bother to speak it.  It had to pass through [i]me[/i] first.'.  And in a way, that meant that Myra was almost self-regulating.  Almost.  Still, there was no failing in the love she had for her daughter, and so nobody missed her more.

Now, when Sara asked Kate to lean against her, that led to a definite question of 'Why?'.  No one had made a request like that of her, just out of the blue.  It was an unexpected thing to ask.  The only thing that Kate could think of was that she had a reason, and that it wasn't the light-haired woman's habit to lead people astray.  For some reason, the thought of it made Kate feel...anxious.  Couldn't really pinpoint why, but after a brief hesitation...she did, and Sara continued, giving her a slew of questions.  At first, the Brunette simple wanted to answer them all, one after the other, as bluntly as you can imagine.  But this is not what the Lieutenant wanted.  She was asking [i]one question[/i]...and it was not an easy one.

Who...and what?  It wasn't just a straightforward answer, was it?  It sounded more like what Sara was trying to say to her was...

[color=f7941d]"Many people said that I should...but the decision was mine.  I can't speak for humanity, though.  Only me."[/color]

Hopefully, that was an adequate response, because...in some ways...she didn't know humanity from the Titans.  Kate felt that...as much as the sleepy giants appeared to be so aimless and vacant...they were purposed, mindful, conscious on some strange level.  They may even have been withdrawn like she was, previously.  It was because of such a fugue-like state in her past that she began to wonder what the Titans really were.  And after learning all that she had about Eren's ability, that line between their two species grew much thinner.
