Sure, for Book 1. But that excuse goes out the window when she shows no indication of actually learning from her experience while acting like that.
Hell, in Book 1, there were actual moments where she did doubt herself, in scenarios one would expect it to happen. But nope, in Book 2, she's suddenly Ms. Know-it-allPowerhouse, despite there being no reason for her to actually think that.
I'm fine with how she acted in Book 1 for the most part, but for her to act the same way now, shows no sign of character development.
