I am still struck by all the names.  We are late in the game for more mysteries, but time and time again we have seen names turn into people later in the story.  One of my predictions for 
Season 3 was we would meet CJ.  Other examples, 
Saul says his mom lives in Annihiem (spelling?) we meet her.  
Angel's girlfriend.  Even after we meet her changed, she is again mentioned, that the zombies dug her up.  This makes no sense to me.  Five million dead in LA and they are compelled to dig up someone who has been dead and buried a couple of months.
Samantha's daughter was named 
Hope.  
Sean.  
Randy, etc.  
Maybe KC's style has changed to confuse us, but I love call backs.  Even obscure 
characters like Max.  Max is seen with the 
water truck, but it is not him when 
Victor does the Trojan horse.  But, we hear that Max is suppose to help Hope get from 
the hospital.  Then, we have Max with actual lines as he helps CJ.  He comes back again because 
Tanya calls him about the Earthquake, right?  Why am I hung up on Max.  Here is a character that could have been substituted by another more established character,  but Max becomes an actual character that is trusted by both CJ and Tanya. 
So, back to Austin, is he really just linked to another case or part of Inks 
file?  If it is a different case, is it tied to Ink's sentencing?  It was a plea deal.
Ok, back to Victor.  
Michael is really unforgiving.  He does not want Victor with him, but in 
chapter 40 part 1, Michael is quick to dismiss 
Kelly's concern about rushing and the investigation.  Michael says no one got hurt... Another mystery...
