I'm thinking about the chapter cover, and what appears to be just four of the team around the fire.
Obviously I'm concerned about the possible deaths of two team members, but I don't really think we'll see that. I find it very hard to believe that, after all these years, Minna would kill off two of our beloved characters in the last chapter, with nothing but an epilogue to say goodbye to them.
But if we assume that two of them will die ... Minna said that she was going to end this adventure as originally planned. The original plan seems to have been that she would go on and have adventures in the other nations of the Known World. We've done Denmark and Finland. How could she have planned to have adventures in Sweden or Norway, without Emil or Sigrun? Or in Iceland without Reynir? Therefore, if she intended as part of her original plan that two characters would die, they would have to be two of these three: Lalli, Onni, Mikkel.
But, again, I can't imagine that she will kill off even one of those three in the last chapter.
Well, except maybe Onni.
