Round 13 is now closed - but not to fills! Head on over to round 14 for new prompts.
Please use spoiler warnings for Age of Ultron. Otherwise, prompt away! And, remember, you can always go back and fill prompts for previous rounds, too. ;)
* Put [FILL] in the subject line when filling a story.
* Multiple fills for prompts are not only okay, they're encouraged, as are multiple story requests.
* After you reply to a prompt - posting your story in direct response - please also post a comment to the fill post, with a link to the thread of the filled prompt. For those archiving their stories on AO3, feel free to post to the comm's collection.
