Hi,
Currently, Quills - when activated without activating other Spines powers, will cause your character to maintain its spines - this includes through things that dont use spines, like Cross Punch, but also just when idling around.
However, once you use another spines power, that spines (which has redraw/gets put away) will take over and then proceed as normal -- you'll put them away if you Cross Punch, they'll disappear after X seconds, etc.
So..
Suggestion: Make the Quills perma-spines look stay active over the other spines, so you always display spines when quills is active. 🙂
