So, as I’m writing the second chapter, I come to a section where the heroes are surprised by a deadly force, and I realize that I need one of the heroes to die here. But I’m in a bind because I realize that I need all of those characters later. What to do?
And then it occurs to me in the most obvious fashion: Red shirt. I’m looking forward to going back through the first chapter and adding this new character…so I can kill him in the following chapter. Muahahaha.

Nice…I was thinking red shirt while reading the first paragraph and then laughing with you in the second.
Heh. As a collegiate sports fan, I assumed the different (but workable) definition of red shirt. Then I was going to leave a comment about pulling a “star trek” but realized that “red shirt” might be a star trek reference. Sure enough, wikipedia set me straight.
