The concept for Twice Shy, my work of fanfiction about Robert as a vampire, originated with an anonymous question I received on Tumblr: do you think robert would enjoy being a vampire?
For posterity's sake, my original response is below! I'd recommend reading the story before reading these notes, as they give away some of the plot developments. (There's not a lot of plot involved in this fic, admittedly.)
Robert Grove would have a great time hamming it up as a vampire. He’d wear a cape. He’d hiss. He’d insist on the Cornley Drama Society putting on more vampire-centric plays, largely because he’s now the obvious choice to play vampiric characters.
There is not a chance Robert is nobly going to abstain from drinking human blood. He would attack strangers if he had to, but he’s a coward who wants to avoid serious physical conflict, so he’d try to persuade people to let him drink their blood voluntarily.
This works out fine at first; Sandra is happy to be a sexy vampiric victim! But then Sandra decides she’d prefer to be a sexy vampire, and Robert immediately agrees to turn her. After all, if they’re going to be putting on more vampire plays, it’ll be good to have someone who can play female vampires as well.
So now there are two vampires in the Cornley Drama Society, and Robert’s main source of blood is no longer an option.
Max and Annie agree to let Sandra feed from them: Max a little nervously, and Annie with surprising enthusiasm. Vanessa, very nervously, lets Robert feed from her; she’d really prefer not to have her blood drunk, but she’s worried about Robert not having enough sustenance and she doesn’t entirely know how to say no. Chris, having repeatedly insisted there’s not a chance that Robert will get any of his blood, eventually gives in because he’s worried about Vanessa and wants to ease the burden on her. (This leads to a very confusing sexual awakening for Chris, naturally.)
And those are the thoughts that ended up becoming Twice Shy! Fun behind-the-scenes fact about this story: I originally only planned to have one scene with Robert feeding on Chris, but, writing the first feeding scene, I found myself going 'wait, no, I messed up by including the anaesthetic venom; it's not hot if he's not in pain.' I was forced to engineer a way for it to hurt.
