There's no evidence

A foreign student, Cecil, remarks to his room-mate, Phileas, that he just bumped into a Japanese ex-prime minister.

...

Phileas: It can’t be.

Cecil: It’s true. He just glided up in one of those Double Crosses. He’s parked in the field.

Phileas: Did he say anything?

Cecil: He looked as if he wanted to ask something, and so I said, “It is you, isn’t it?”

Phileas: And?

Cecil: And then, well, he just looked a bit blank.

Phileas: It wouldn’t have anything to do with…

Cecil: What?

Phileas: What the subtitles said he had said on TV the other day.

Cecil: Maybe it was the subtext that made him resign.
