Missing person

I was somewhere with Hui, Hap, and Jason. We are having an intelligent discussion about missing person and how to go about locating them. Before we knew it there are a bunch of kids try to sign us up for a donation, and they need to get our details. So we wait for a while and when the paper was passed around, Jason starts filling most of them with the name of the missing person, but being indexed 1, 2, 3, etc. He said that if they are to find all these indexed ppl hard enough they will find the missing person.
Then he was asking me where did my name Pin came from, or what it means, I looked at Hap and he looked at me dumb founded. I casually asked him so is “Jason” came from Jason the argonauts? He said, that is one way of looking at it yes.
