On the discussion re merchants
The simplest in-game answer is that there are merchants around Elpis, some with an explanation like the gemstone trader (IIRC she says she's got some kind of familiar that eats bicolor gemstones), others being harder to explain like the multiple junkmongers selling player equipment that, from a lore perspective, would be outlandish garments no respectable Amaurotine would be caught dead in. (Some sell the PVP-copy sets and others the Neo-Ishgardian sets.)
Thinking over Myths of the Realm, I put a finger on something that was bugging me...
I dislike it in something of the same way I dislike the Sorrow of Werlyt, in that it spent a large chunk of its time introducing a cast of characters with one-note personalities for no other purpose than to kill off every last one of them by the end of the story.
On a totally different track, I checked the variable cutscene in the Ocular.
Confirming that if you turn off the "reflect quest progression" button, the cutscene ends just before Gaia would have arrived.
Other than that, the scene up to that point mostly has the same script either way, besides one line where Beq Lugg mentions working with Unukalhai.
Also, for anyone who picked the line about coffee biscuits when Gaia was asking who you were, that answer doesn't really make clear that she was just joking, which she says straight away if you ask whether she's lost her memory again.

I don't know, but it seems possible.
Just after he left, I flew down to Moraby and checked the Mark of the Spinner in case he was there, but he wasn't. Though it would have been lucky to find him on the first try even if it actually is a thing that can happen.
Purely speculative, but if he does turn up, it would be neat if he gave little bits of extra lore about something useful when you found him.
