It starts out with our second of many Will Eisner stories I'll be looking at. This one starts with a map! There's not much to it, but it might help with a Mythic West-themed campaign.
And yet, Heroes surrender at odd times in stories all the time. Sometimes it's because the writer needs the main character to sit still long enough to hear some juicy exposition. Sometimes it's to add suspense to the story with a deathtrap. Sometimes it's just to draw out the story longer.
The first two of those three reasons are legitimate excuses for an Editor to ask for a save vs. plot from Heroes to avoid surrendering. Some players might balk at this, but it is VERY comic book-ish.
