When someone needs help, you step in. It's as simple as that, and besides it looks like they have a lot of work to do whatever they are doing. And it's nice to see the non-nobles hard at work.
Kihal imagines that they have a hard life being so close to nobility, but then again, so does she, as she can't simply make Brecker disappear. He's staying, and hopefully, this isn't as hopeless of a trip as it feels.
But nobility is hard headed and hard hearted, but here is someone that looks both awed and grateful, pausing to thank her even does she has work to do. This is a normal person, not one caught up with status, and also, one who is kind and compassionate.
She's trustworthy. So, Kihal pauses, and let's her words fill the space between them and explain a little more about Popo and how things worked, and why she's here. It's wonderful to find someone kind enough to listen, who won't laugh at her, just a little alarming to see her own stubborn trust in a prince of all people.
But sometimes nobility is tricky. But it still floors her, and Kihal takes a deep breath. A new beginning might be just around the corner even if she can't see it quite yet.
