I think it was the second time when you run into them I think? It has been a bit tbh, first convo is just 'Familiar Voice 1 and 2, and the second convo has a name is revealed... I'll just keep spamming (every 6 days) to see if I can get both names revealed to see if that is the trigger..
Edit:
Ah, got it, the event at the Outpost is at night, I kept visiting in daylight.
I was able to also get it through finally, tried during the night like you mentioned and at first i thought it wasn't working until it did, didn't realized it was supposed to be exactly midnight but yeah 😂 also nice to finally put a face to a name, seems we already gotten to know more about heath even more so on my run at least, tried to see if there was also new dialogue when you meet him at the battlefield like if you have good enough rep like with barrell but its just the usual fighting for now hope there's more to come!
