I know that there are possible explanations as to why Pakunoda did not read Hisoka's mind. I just wish they mentioned or at least clearly implied one so that the viewers did not have to guess at it by making assumptions.

The author makes essays about just one of Kurapica's powers, but does not spare one sentence to explain this. I don't think it is terrible writing at all. I just find it a bit uncharacteristic for this show.
