I was rereading the series and it seems to me that Carlos is no longer Harry's friend. Carlos knows that harry is "working the problem" of the black council from the other side but is constantly suspicious of him. He puts a tracker on harry then gets Harry's only other friends that are wizards to accuse him of being disloyal. The whole time giving the Morgan line if you have nothing to hide let me interrogate you until I believe you. When Harry needs to talk to people to prevent from being thrown out of the council Carlos puts him on a security detail so he can't. And when Harry asks where this is coming from he is told Anastasia. But if he switched sides to team merlin after the beating that Molly gave him it could be part of a plan to isolate harry to either take him off the table for whatever the upcoming starborn event is or to force harry to tow the line for the white council. Either way I expect that it will be Carlos who comes after harry next and will probably be in charge of monitoring harry now that he isn't a wizard anymore. I also expect that Carlos now blames harry for what happened to the other wardens with dracul

we are told its Thomas but every time someone sees him there is a disclaimer that he is so messed up that they cant be sure.  what if he is a Trojan horse to get onto the island?

I don’t understand the actions of Luccio in a fist full of warlocks. We have seen Morgan try to cut people’s heads off for even the slightest infractions (granted Morgan thinks everything harry does is dark magic but still) and Morgan has modeled himself on how Luccio has acted in the past. Spoilers after this point.......... but when have Luccio with someone she knows is a user of black magic.  Someone who is the leader of a cult of warlocks.  His people are coming to kill her and free him and she doesn’t do anything but neutralize his magic.  they were going to kill molly without a trial if it wasn’t for Dresden but Kemmler gets his day in court.  Why didn’t she cut his head off the second she found out they were necromancers? I find it difficult to believe that warden justice favored the accused rights during the wild west more than it does now.   I understand from a story perspective Kemmler has to live but if a beat cop let the guy go that ends up starting WWI how does that cop does not get to be head of the wardens
