Surprise did not being to even cover what Kaito felt. At first, he was only curious to see what Camie would do when she began to approach them, following her movements with his eyes. Mild curiosity immediately changed to full-blown surprise and astonishment when she reached up to kiss the detective that was still more or less in his arms.
His poker face faltered as he stared blankly at the scene almost directly in front of him, never imagining that she would be so unpredictable even for a tease like himself. Shaking his head, he even felt sympathy for the poor detective who was clearly, obviously, overwhelmed by the unexpected turn of events.
Turning his gaze to the compulsive trickster beside him, he decided that a little punishment was due, on behalf of the embarrassed detective. Looping an arm around her waist firmly, he pulled her in and caged her in his arms before leaning in to whisper into her ear.
“That was very brave of you, wasn’t it? Would you like to try again with me? I’m more than willing, unlike our poor Hakuba-san.”
“Ah, y-yes, I’ll let… let you handle this, Kaitou-san, thank you…. ah, I’m going to go get some tea, now… I’ll… catch up with you both later.”
With Camie in Kaitou’s arms and his own self free, the detective slipped away and into hiding. Presumably to put the kettle on (which was actually the truth).
Tea fixes everything, right? Something like that.
