[Graham had forgotten about the party until the second letter went out. He wanted to go, but totally neglected getting a costume. So, with not much in the way of ideas, and the city pretty much having moved on from selling costumes, he had to improvise.

Heroes sure do love their parties. A problem arises, they knock it down, celebrate, and the process repeats itself! What a sad story. Things must get monotonous for everyone!
