Hakuba absent-mindedly pulled out his phone as they arrived at the lab, flipping to the picture Kaito had sent him.

"Hey, is that the hairclip?" Conan asked. Hakuba shrugged.

"Maybe. We'll know when your friends arrive, since they have the hairclip in question."

"Then who sent the picture?"

"A relative of one Kuroba Miki. Found it flipping through family photos, apparently. You, know, the woman whose plane blew up ten years ago?"

Conan fell silent, staring at the wall in the distance.

"Blew up in a plane, huh? If she's the woman I met who was friends with my mother, she was a very kind person and your friend is likely right," he finally voiced. "I was wondering why she never contacted us after a certain day..." He took out his phone and flipped it open, then typed something, closing it immediately after, grabbing Hakuba's curiosity.

"Who?"

"Someone who would know more about that incident."

Hakuba raised his eyebrow. Who would know more, seriously?

"Kudo Yuusaku."

"Ah."
