Okay, I don't know how to have a good discussion with someone who clearly has a different definition of what constitutes a "person". I didn't like Murphy because of her "function" as the normie of the group, I liked her because of her personality, of her way of interacting with people. If she came back with Valkyrie powers and some conflicts of loyalty, that would not change her basic personality, that would just add conflict to her relation with Harry. Her intrinsic value to me as a character is not in her position as the "one without powers" in Dresdens coterie, but in what she provides as a person. So, sorry, but I don't put much trust in your predictive powers, which you clearly are trying to exercise here. Murphy will be as much the same person after returning as Harry was after coming back from being nursed back to health by Mab.
100% agree with this take above.
However Harry didn't change, he always had magical talent, and when his brain was occupied with Lasciel's shadow, he had to deal with rage issues then as well when it came to Hell Fire. With the Winter Knight's Mantle he got a bit stronger, and had to deal with primal urges he didn't have before, but he got a handle on them and remained Harry.
If Harry went through all of that and we can say he didn't "change", sure that's a valid thing to say. Though to be honest, people evolve and change according to circumstances they live through, I don't think it's just a matter of the physical parts (ie being a wizard or human, etc), that's such a limiting view, but ymmv.
Anyway, we can only say he's still him because we've seen him after each and every one of those "challenges" or "transformations" coming out victorious, so to speak, still himself. We have not seen Murphy after her "transformation", so how would it be possible to be so sure that she won't be herself? Because of the physical aspect? That doesn't hold up.
Her body perhaps, but it won't be the Murphy you remembered and loved. True, you could love her more, or sadly you may wish that Jim had let the dead rest in peace.
Maybe not the one you loved/liked, if you ever did, because clearly you see her differently than some of us, but this is a repeat argument from 3 years ago, with no evidence to support it. We have not seen the aftermath for Murphy yet, and nothing similar is touched on the mythos of the series yet, so, how she comes back, if she even does, "changed" or not, is still mostly a mystery until future books.
And even if she changed, I dunno why it wouldn't be something the fans of hers wouldn't want? Why assume the change would be a bad one in the first place? But even if it was, Harry has taken blow after blow, jobs and mantles on himself and he's, let's say "evolved" not necessarily in a positive way, he's extremely flawed at this point, but for most fans, it seems, it has made him more interesting. Murphy fans will know if maybe the same applies to her.
