In episode 2, Hashiba plants a phone in the classroom under instruction from
Kobayashi, and then has Ms. Hanabishi show it to the class, asking who it
belongs to. Hashiba replies that it belonged to their murdered teacher.

Somehow, from this sequence of events, Hashiba is able to deduce that the
teacher-killer is in their class, as he reports to Kobayashi when he blusters
his way into the interrogation room later.

I don't follow Hashiba's logic here. We did get those shots of [an eye darting
around (nervously?)](https://i.stack.imgur.com/2aAQh.jpg) during the sequence,
but I'm not sure what to make of them. It can't be that Hashiba noticed
Hoshino (the killer) acting suspiciously, since if he had, he could have just
told Kobayashi about her right away. But nobody besides Hanabishi and Hashiba
himself said or did anything (besides the darting eyes) during the staged
phone-finding... so on what grounds was Hashiba able to conclude that the
killer was in the class?

How did Hashiba conclude that the teacher-killer was in their class?
