Through Another's Eyes
Do you have a minion? a sidekick? or even just a friend or relative? failing that, a bystander!
Write a vignette about your heroes exploits from somebody else's vantage point. It may be a chance for a sidekick or minion to shine and be heroic themselves! Whoever your choose, and whatever they do, they should be involved in the story themselves, as should the hero in question. They could be heroic, they could be a victim, they could be a bystander.
The thread could be written in third person, or in first person (such as the 'others' account of the event to his/her diary, a reporter, or just a verbal account).
When/Where: Your choice.
How Long: At least one page length in your word processor of choice.
