It is so very hard to write when you have far more opinions and conclusions about the situation to make than your character does. I had to keep backtracking and deleting stuff because it was actually more than Glen would have bothered verbally concluding or actually thinking through.
But he did show some limited ability to think critically. Technically. He made conclusions.
Correct conclusions? Probably not, but hey that's what Glen is for. To have his hopes and dreams crushed before he can even have them.
