The two parts I’m eager to find out about Dawntrail’s aftermath relating to Sphene are Sphene’s crown and Solution Nine’s eventual exodus.

The first is more likely to be addressed since the camera lingered on it in the stinger, but we were told in a single line earlier on that Sphene’s regulator is “special”, so I doubt this is the last we’ve seen of her but I couldn’t guess in what form she comes back.

For Solution Nine, we’ve been told that their birthrate is in sharp decline and part of that may be attributed to Levin Sickness, the same illness Sphene and that boy suffered from. Unless the lightning under the dome stabilizes or they manage to shut it off, I don’t see Solution Nine being a long-term solution for their society on the Source. Or Alisae just hits the boy with the porxie cure for tempering, which is basically the same thing, and everyone cheers and it never comes up again in the future.
