List of Emailed Prompts (as of Feb 15)
More than 10 years after the war, someone's making a movie of The Great War, and is hiring as many of the actual participants that they can for cameos and sometimes more. Harry winds up cast to play Snape, who sees the preview shots and storms onto the set to demand an end to this travesty.
In order to find out if Voldemort is reaching Harry, Snape takes a potion that lets him share Harry's dreams.(He could find erotic dreams, or find himself as the hated taskmaster and decide to correct Harry's misunderstandings of him, or wind up trapped in Harry's dreams somehow.)
While Snape's recovering from Nagini's bite, a distant cousin dies--leaving Snape as the last heir to the Prince line. He needs to take a mate from a longstanding wizarding line--Malfoy, Potter, Weasley, Longbottom, or Black--within a year, or Dire Things will occur. (Possibly, he'll be driven to mate with whichever of them is closest when a year is up.)
Snape survives Nagini's bite by triggering his own transformation into vampirism. Harry finds out, and offers to be his donor.
Albus Severus is the reincarnation of Severus Snape; Harry discovers a very problematic crush on his own son.
On their first wedding anniversary, Ginny gets Harry a magic candle that grants "your greatest desire" when it's blown out. She's thinking she'll get pregnant; is not happy when Severus appears in the middle of the cake.
During the hiding-in-the-woods time, Harry has found a way to secretly sneak into Hogwarts to steal supplies. He gets caught by Snape, who demands sexual favors in exchange for his silence.
Gay marriage is legal for wizards! Unfortunately, with typical Ministry of Magic incompetence, it's also *mandatory*... all gay wizards and witches over the age of 18 have two years to get married or be stripped of magic. Harry dithers until Snape's the only gay wizard left.
Snape's ghost haunts the Shrieking Shack. He convinces Harry to brew a potion that will let a ghost inhabit the body of someone living so he can get out and do things. (Potentially, cue botched potion-brewing with results of author's choice.)
Professor Snape has a scrying-glass that lets him look at anyone at Hogwarts who is masturbating; he uses it to inspire his own wank sessions. He realizes he's never seen Harry in it, and gets obsessive about trying to catch Harry at the right time.
Post-war, Harry runs way to America to become a survivalist: guns, bunkers, planning for the end of the world. After the Ministry tries sending several people to bring him back (and they all get pounded and nearly killed), they send Snape.
Harry works as an undercover Auror investigating magical crimes; a series of gruesome murders has him looking for a suspect who apparently looks just like Severus Snape. Since he knows Snape is dead, this must be an imposter. Harry vows to clear Snape's name of yet another set of false accusations.
Snape shows up a few years after the war, a bit damaged but very healthy. Harry tries to find out how he survived; every time he asks, Snape tells him something different & plausible (bezoar/rescued by house elves/draught of living death/immunity to Nagini's venom etc.), and it takes Harry a while to figure out why each answer isn't true.
Professor Snape keeps assigning Harry detentions, but since they're no worse than the work he has to do for the Dursleys, he spends most of his time whistling happily to himself. Snape is determined to find a punishment that *works* on the brat.
A malfunctioning protection charm placed over Hogwarts causes people's clothing to disappear at random. Harry & Snape discover each others' true feelings, or at least, their true physical reactions to each other.
