[The tone and urgency is enough to get her attention. In fact it's familiar, reminding her of only recently. Come to think of it - he's been like this a lot recently...
However she doesn't question it. Eyes wide in question, she simply nods.]
[Luckily, for Yuuki, it isn't difficult to find Zero. So in touch with his sense and presence, she's often aware of where he is or how to find him. She doesn't waste time, either. As she approaches, though, she becomes aware of another presence -- two others, actually. All things considered, it's the female vampire, though, that draws her attention. Just the other day Yuuki interacted with her. And now-- well, Yuuki's aware of the absence of someone who, undoubtedly, held a strong connection to the girl standing before her now.
Coming to a halt, Yuuki looks questioningly to Zero, back to Saya, while simply remaining aware of Hei's presence. Heart clenching, she doesn't ask the most useless question.
'Are you okay...?'
Of course she isn't. Zero wasn't either, that one day, a little over a year ago. No. Her brows knit, eyes creasing. Sad, and with a heavy heart, Yuuki looks up to meet Saya's gaze.]
