The Professor's moon walking was highly distracting, it didn't help that she was already finding it hard to pay attention through all the others saying what they'd do, some of them were just wet blankets. By some great miracle they managed to sneak into the Forbidden Forest without running into Mr. Firth and obviously they're alive if they get to be thinking of a way out so why waste the time hugging a tree or setting up camp for the night? Might as well go looking for something epic!

It only made sense to.

Lex continued to follow the Professor's movements, even after he went pointing out the window. Her attention was only waning a little but she caught it right back at the next question. One she knew the answer to...sorta.

"It's because it's not like all the other stars that move around in the sky and fall in different places depending on the time of the year. No matter what month it is it'll always be right there for you to identify because it's a supposedly fixed point, which is good when you think about it. Can you imagine getting lost in like June if the star only came out in December???"

Heh, bet they'd go looking for a centaur's help then.
