This video should explain everything hopefully, and it also shows a lot of whats going on with my problem.
"why not just use the bone to make a shape key for blinking then remove the bone after transfering it weight to the head"
this ended up working for me!
I made a shape key with the uppereyebrow bone (Highhigheyebrow) using the CAT5 (CATS?) plugin, then I renamed the Vertex Group for Highhigheyebrow to Head2, which applies it to the Head2 Bone, and this works!
