Alt-text: "Don't worry, Book! The cavalry is here! And very afraid!"
I've personally never been in a situation where I could have played the hero ... I would love to imagine that when it comes down to it I'd overcome my fear and let the adrenaline fuel me to do awesome stuff.
But, you know ... on the other hand I might go into full panic mode and just run away as fast as possible. Or freeze and do nothing. Kat might have a similar problem here.
