Personally, I'm not so sure about the PI. The first time I saw him he said that he had met with Daniel once. In following interviews he said they'd meet several time a week. He's saying what we want to hear, but it is another illusion?
I think he was talking about two different things. The ex boyfriend of Anna that Daniel was staying with in California was friends with this PI. That's how Daniel even knew who he was and that he was a PI. As a friend of the man Danny stayed with, he visited the apt. frequently and saw Daniel frequently. But then Daniel asked to meet him for lunch or some such to talk about his mother and Stern. I think I have it right but if not, someone will correct me.
In terms of when they met, he could be talking about when they encountered each other instead of a meeting to discuss employment by Daniel.
In the first interview I saw, Harding said he was a friend of Ray Martino, Daniel's 'roommate'. They had encountered each other several times, including frequenting the same coffee shop. As far as I've heard, Harding said Daniel met with him once regarding concern about his mother.
Daniel and his *not-guardian* Ray Martino had coffee several times a week at the same coffee shop and the PI, Jack Harding, was a regular there, too.
Over the weeks and months, they got acquainted with each other and usually had their coffee together.
At some point, Daniel decided he wanted to talk to Harding alone, away from Martino, so as not to alarm Ray that there might be anything wrong. So, he asked to meet Harding elsewhere and not tell Martino. They did.
They met once and Daniel told him all that, then Harding told him it wouldn't be a cheap investigation to have to travel to The Bahamas. Daniel said he'd have to get back to the PI about the money, then.
That was just a couple of weeks or less before Daniel went to Nassau and died.
*not-guardian* - I say this because he really was Daniel's guardian, so to speak, but not legally or any other way - because Daniel was 20 and didn't *need* a guardian, unlike his mom.
But "friend" sounds weird or "roommate" doesn't really describe it, either. Sometimes I call him the "landlord" so it sounds like Daniel was just renting an apartment from him, but he was living in Martino's home so someone could take care of him (Daniel).
