[ The rest of the world, and anything she's been working on, are forgotten now, Shaw's tick and voice drawing all of Root's attention. ]

It's kind of like a tickling sensation, or little muscle spasms. Physiologically, my body can't tell if I'm in danger, so the fight-or-flight response gets activated. Most of my blood is being directed away from my digestive system, so my stomach isn't happy. It's letting me know that. But since the reason it's happening is good, it's not uncomfortable. It feels good to be a little nervous, because I'm consciously expecting to feel more good things. Like this.
