In the aftermath of PT and BG, a lot of Carlos hate was thrown around on this site and others, Carlos is blind, dump, should trust Harry etc, etc. In the post 12 Months discussion there is little being said about Carlos and Harry interactions ,and Eb and Harry's interactions.

What do you mean? I saw a lot of discussion about how Carlos and Harry suddenly seem chummy again.
I don't know. I think Carlos  had time to think and realize he was in the wrong. I am glad for that and I welcome him, but for now I won't apologize.

Agree with Winter and Demonreach.

I also thought Mab had trapped the one in Lea, but she then said "vanquished" and I am not sure what the word implies in this case.

I imagine Cat Sith is on the wind and I am not sure if Nemesis just jumping from a host won't kill it. I am not sure why it remained in Justine, but I imagine it has something to do with the baby.

Nemesis is the Outsider He Who Walks Beside.

This. And Mab said she vanquishes one so I think what happened is that she literally sent the thing in Lea to the Outside. I don't know how but the tricky part seems to be to capture the host and split it from Nemesis, because just killing the host means that Nemesis is free to conquer another one. Instead,  if it is sent to the outside, it can't be back (at least, for now Mab is operating as if sending it to the outside removes it from the game).
I also think Nemesis has puppets in all the major groups. That is why I said it would be funny if there was a nemfected blampire who was casually squashed by Harry. But in truth, I think Drakul would have probably spot the puppet.

Kurtis, I know you meant Optimus, but your Optimistic made me laugh. Self-correct, right?

Mm, this is interesting but I think Harry's deal with Mab prevented her for some things, even if her host obligations have been challenged by the Winter Knight behaviour.

Small digression: I don't actually think what Harry did was so bad from the Supernatural etiquette point of view. He did not say "I am going to kill you" he said "die". I think words matter,  forms matter, and a supernatural member wishing another one ill should not be a problem. A direct threat would have been more complicated. In my opinion, not so bad either unless Harry said "I am going to kill you right now", which of course would have been unacceptable.

Back to the point. I think Lara began kissing Harry thinking she was not going to feed from him, her hunger previously seated, so was not worried about the burnt. Then. I don't know, he smelled Harry or something and her instincts took off and she began feeding. And it suprised me that she was not surprised herself by the not burning.

About the overall book, for me Battle Ground was that book that had more things that I liked vs the things I didn't like, even though the thing I didn't like, I hated with a passion. Twelve Months is more like a 50/50 and I'm being very generous there. And again, I repeat that is not the lack of action or a lack of "a main villain" like I see pointed out in reviews that are not so favorable of this book around the internet, it is about other deeper things, some of which I've mentioned here.

That is what people is complaining about? Not my case, clearly.

Not only messy, but true love doesn't work that way, if a person loves their partner truly, it doesn't matter how the partner feels about it, it continues. True love isn't logical, that's what sets it apart.  Just a thought, it's been centuries since or if she ever felt it that Mab has had felt true love for anyone.

It does matter though, that is why Harry was not protected when he was with Luccio. He Loved her but she did not.

Ah yes,Bad Alias, time of being together, yes that seems to count.

Something I agree with LaraBeck and it has bothered me for a while is that when Jim introduced the idea of True Love is was supposedly be very rare, but Harry had it twice, Thomas have it, Arturo have it, I think Inari had it (I don't remember right now if it was True Love or just love). I bet Michael and Charity and Will and Georgia will be True Lovers too!
