Ghostwriter

Perhaps, by chance, they come upon something that rekindles hope in them, and could solve some problems in the (very) short term. Like rumors of others who have created a boat that'll get off the island soon. Or perhaps that something had survived against all odds. Hopeless moments are fine, but not in excess. Nothing spectacular, but something that is helpful.

But there is a catch. It wouldn't be a good story if all of their problems were immediately solved. While Dime may be okay with this arrangement of traveling companions, not all strangers would be too happy to encounter another reptilian. If they encounter other survivors, they may be guarded, or if they do find a means off the island they might have to get creative to get the small group on it. Something that pushes them from sticking too long in a hopeless spot.
