I’m so lost idk why

So I’m so lost on what’s going on overall in this book. Maybe my attention span is not great maybe other reasons but I have a few questions overall on this secondary series

From what I gather at the beginning of the book the governor’s brother was murdered by bleeder. And the whole book consist of wax trying to protect the governer?

My main questions are

1: I thought Kendra needed the bones to mimic people? Did I miss something at the end of era one? I know it’s said that they can mimic without the bones but not perfectly. Was that barely established here?

2: Wax’s ability’s overall. I know her can push and he has a steel bubble. Then something to do with his weight? Can someone explain? I also assume he’s using a steel bubble 247 to push away bullets but in that case why would all the other metal be pushed?

I’m only on chapter 18 so don’t spoil too much unless I otherwise stated it.

I feel like I have no idea overall what’s going on in this book. I have no idea why bleeder is doing this act.
