how do you do fellow kids

Bury me with you in that unmarked grave, my bones will rest easy next to your bones

At the beginning of HtN when Mercy demands Harrow's age, we're all pretty well in agreement she was really asking this was the result of their efforts to open the Tomb, yeah?

But somehow it just clicked for me. The emotion that plays across her face and through her whole body, the "unalloyed, full-bore relief"... Yes it would be a problem on many levels if John's kid showed up...

But also, until the very end of the book, she fully believed that kid would be hers. She didn't know everything Wake had dealt with in the end. I mean I've known this but it just clicked in this context. Based on everything she knew, if Harrow had been That kid, she would have been John and Mercy's daughter, LIKE... YEAH I fucking BET confirming she wasn't was some intense fucking relief!!

go loud

They are both locked under water in Harrow the Ninth, with Pal literally being stuck in the river and Gideon figuratively in the well. Harrow kinda frees them both from that but also Harrow is the one who locked Gideon away save her and Pal locked himself away to save himself.

The fact that they both shared a body with Harrow and Cam and both Cam and Harrow are physically damaging themselves to keep them here even though both of them would rather they didn't.
