"One of the sensors tracks movement via air displacement. It's useless in a crowd but it's great for spotting something that is there even when it can't be seen.

He turns the helmet in his hand and looks at the skull like faceplate. "Red Hood was the name I took for myself when I can back. Partly to distance myself from who I had been but partly because it's a name that has history with me. It was an alias used by someone else a long time ago. Someone who became a monster because of other people's choices. I use it to remind me of the line in need to walk."

He snorts and looks up. "Fuck, you've got me talking serious today. What else did you want to know about the suit?"
