Let me quote Hunterpedia for a refresher of what happened:
However, before they get the chance, Zazan's squad detects them and Ponzu is the only one able to escape. When Pokkle was knocked out, she immediately runs for it. Knowing that Pokkle won't be eaten immediately, she rushed to write SOS messages in blood and uses her bees to bring the message to the strongest Hunter nearby--who happens to be Kite. When she finally decided to go back to the border, she is shot and eaten moments later by an officer from Zazan's squad.
When Gon arrived at the scene much later, all that remained was a puddle of blood and cloth and he looked angry.
Did he realize the victim was Ponzu?
