Random Theory (Pong Pong Tree)

The dead body in episode one is a person intentionally poisoned from the pong pong tree. I didn't see any blood in the water. I think the talk about the poisonous pong pong tree seeds was very intentional for the viewers.

Also.. random thought.. why risk having poisonous trees around a resort? Seems careless to me. That fruit was all over the floor of their suite.
