Okay, I'll have to check that out. I don't know if R* is known to troll players or not but it seems crazy to put this guy in and not have something behind it.Oh yes. There is quite the Reddit community. I wouldn't say it's to the feverish dedication of the Mt. Chiliad mystery in GTAV but there's a pretty dedicated bunch trying to find him.
If you've gotten to the epilogue there's also a neat detail
You find Gavin's friend in Blackwater, years later, even more desperate, in the same clothes only they're ripped and dirty. He seems like he's about to lose it even more completely.
Thanks.
