In 
Chapter 16 part 2, @ roughly 7:05-7:11, 
Pegs radios back to 
the tower to speak with 
Lizzy ("I need to speak to Toucan.") after she has the 
Latch nightmare again when she, 
Michael, and 
Kelly are at the 
beach house. But 
Angel's call sign is Toucan, not Lizzy's. Of course, in the next part of the chapter, 16 part 3, Angel and 
Kalani are going to give back Latch's body to 
the Mallers. Unless I'm not thinking this through properly, that would mean that she A) didn't speak to Lizzy at all and just to Angel to ask him for the favor...or B) She spoke to Angel and then to Lizzy. 
I just thought that was a little...inconsistent.
