I love this episode. After hearing that a reviewer on YouTube was going to review it I thought I'd check it out. This might be the best animated think I've ever watched. It pulled on my emotions and it tugged even harder when I learned this episode was a response to 9/11.
In this episode a fire destroys most of Lakewood Elementary and the episode follows four different stories in the aftermath of the fire. This is similar to 9/11 because a lot of these stories probably happened to real people and there families surrounding the event.
First of Arthur's Father makes it out of the fire but Arthur is worried that something else might happen to his dad. Second Buster who was at home asleep during the fire befriends a man who was injured in the fire. Then Sue Ellen has her journal destroyed in the fire. And last but not least Binky after seeing the flames his self develops pyrophobia (or fear of flames)
There's an ending that I'm not even going to spoil for you here. You can find the episode on youtube.
