I will say I was happy with the Murphy of these two chapters.
She's still present and has Harry's back, but she didn't try to leap into the water and fight the kraken or even shoot it. She took an active role, doing things like getting out a flare and lighting it, or giving Freydis a grenade, but she's acting well within her body's limits and not blindly charging in and becoming a liability. I should have had more faith.
She seems to be taking over some of the best parts of Butters' role in Dead Beat. She's a mortal, in over her head, but still able to help through grit and competence. And she gets to be the reader-stand-in for much needed world exposition. (Not everyone has been researching the Ethniu myths since Peace Talks came out! And there's going to be a lot more that we don't know.)
Their relationship even felt more real and healthy than in their first chapter in Peace Talks, where it felt like they were always maneuvering through a minefield of prickly topics. Maybe it's just that they put all the small stuff to the side when things get serious, but it was nice to see. (I'm not sure if it was intentional, but on second reading I laughed at how she's now *physically* "lumpier and pointier than the dictates of romance..." where she was like that metaphorically in chapter 5 of Peace Talks.)
