If you will look at the map, you will notice there are two bloodied enemies (surrounded by red). Plus, all the others were minions, which can't ever be bloodied. That only leaves the two Dragonshields.
Speaking of the red, I thought it was clear, but I've been using a color system to show when a creature has some kind of effect on them. Red for bloodied, Green for Immobilized, White for Marked, Black for misc. effects. There'll be other colors as well, but for everything but marking I've been including the color when describing the effect in the text.
So just so you guys have that information in the future.
