Here's another:

1. After the nautiloid crashes, Shadowheart tells you that Lae'zel must have run off and left you both there on the beach.

2. In fact, when freeing Lae'zel from the cage trap, there's an option to accuse her of having done just that.

3. But why would it ever occur to me that Lae'zel lived through the crash? There are bodies everywhere. I would have just assumed that her body was lost in the crash, or crushed under the weight of debris, or lost in the river.
