Bam and Rachel *potential spoiler answers*

I am approaching ch 400 of ToG and I just have to ask at this point: does Bam and Rachel's relationship ever improve quality wise?

Because at this point it feels just like a campy, circular plot where she can't hurt him, he won't kill her, and he keeps losing friends to her. It honestly is abit frustrating because what's the point of him wanting to protect his friends if he refuses to go all out for them?
