So, I think we have a few options here:
(Please bear in mind that the two bodies was my tinfoil hat speculation for the week
any time I suggest anything regarding it I am very tongue in cheek)
Siobhan is off in her original body and sent someone looking for Sebastien, hence the woman in the carriage.
The creature is off in the original body and sent someone looking for Sebastien.
Siobhan and Sebastien are now distinctly separate personalities residing within their respective bodies but still only one body at a time. Siobhan separated the two far enough and then changed forms and Sebastien can’t remember anything after a certain point.
Her brain is really messed up and it’s affecting her ability to retain memories.
I suspect she’s getting whisked away to healer Nidson to stabilise her, but I’m fairly certain the connection to the raven is gone and part of this might even be backlash from it being forcibly broken (did they ever tell us what the result of that would be? I know they did testing for it. I wonder if the raven is dead. I wonder if the raven was piloting Siobhan’s body!!! tinfoil hat intensifies).
That means she’s going to sleep. To sleep, perchance to dream? A dream could take a single night or it could play out in real time and she would be in a coma for weeks.
We know that Siobhan was the creature’s jail and jailer. But what about Sebastien? Could she be her personality with all her memories but without the seal?
Or, going back to my previous speculation, could her mind be so catastrophically damaged that the seal is basically worthless or even broken - broken before the sun rose, so that the creature was forced to leave her body because it perceived staying as harmful to her and was still under the terms of its vow? Might it be out in Gilbratha at the moment?
Or is the seal still there, on the very verge of collapse and the creature malevolently awaits the moment that she breaks it out while trying to reconstruct her mind? Or perhaps is broken out by someone trying to remove all interference in her head and the creature pilots her body while she’s trapped in her memories? Reversing the jailer and prisoner.
As for Thaddeus Lacer….there are a few conclusions he could come to:
- Siobhan was casting magic on Sebastien and the magical backlash from it being forcibly broken during his attack on her caused him to suffer serious side effects
- She’s retaliated by attacking his apprentice
- He was too focused during the fight to feel Sebastien call for help
- Sebastien got into trouble by casting too much or too dangerous magic or tried to test out freecasting without supervision
- Sebastien is the Raven Queen! (Who am I kidding?)
- Sebastien and Siobhan are both being possessed by the Raven Queen and used to enable dual casting, therefore damaging one damages the other
- Some kind of Vulcan mind meld thing to try and protect her memories but left Sebastien open to backlash.
