Ugh, that should say "Anticipation" isn't an emotion.
The Doctor's long boring explanation for why they're glowing says, "When luciferase oxidizes, it produces bioluminescence. And through some vestige of the truth field the Time Lords erected the last time we were here, the bioluminescence is reacting to our emotions." Which kinda gives away where they are. As does the description of the comic, to be honest. And, also, if you just asked me where they are.
