Charlie is not sleeping because she wants to avoid Reyes who is still angry at her for binding him to his body. Then she has a case for a missing woman and is trying to solve the mystery for Reyes.
This installment was good but it did not advance the plot much. Charlie has a lot of jokes and sometimes if felt like she is a jester. On the one hand she is still very childish, it seems like she is in a game that she knows nothing about and instead of focusing her energy and trying to learn she does nothing.
It seems like everyone has ulterior motives and I really hope Charlie can make some headway.
