His sister is in Japan for once. Gō invites them both over for dinner.
That's a shockingly vague answer, coming from her. Normally, she's all-too-happy to tell him about her latest exploits in court. Normally, she would never miss an opportunity to remind him that he hadn't accomplished anything half so impressive when he was fifteen.
Reiji is marginally better at lying than his daughter, but not so good at it that Gō can't tell he's hiding something. Are they both — no, Reiji looks as confused as he does.

Why is she acting weird about that question, it's not as if someone's brought up one of her crimes at the dinner table.
...Well, she did say she was here on classified work business. He doesn't have much to substantiate that guess, but even if it's only a guess, he'll need to be careful around her.

There. That is a true statement that does not involve admitting to being involved with the investigation even a little bit.
"Be that as it may, if a prosecutor has failed to get a guilty verdict — or if the court has declined to sentence someone to death? I believe a few of the recent cases have been criminals serving out prison terms — it is not the place of vigilantes to correct it."
