title says it all. but i have some crazy and impossible theories...
1) The commandant could be a lord captain: i would say the probability of this is pretty low, since Garten probably wouldn't trust a lord captain. anyway, i was thinking Perkin One-eye. for one, commandant had one eye. this has been my theory since reading Ember Rising.
2) Random idea: Garten could have gotten Jupiter to the Crossing [as it was called before the fall] by telling him that an army was going to attack and that he had assembled another army to fight hem.
3) the Teller: this rabbit could have been a lord captain as well!! then killed by daggler after spreading the story he was told. he might have been forced to tell where Helmer and Picket were.
4) I highly doubt Pacer would have betrayed the cause for anything. i believe Pacer was killed by Tameth.. have no clue how that happened...
5) The Pilgrim is Massie!!! [or at least in my head]
this is a place to share Green Ember theories if no one has done this yet.
The Pilgrim could be Massie. I mean, it's not impossible.
