Recently got an idea for a potential angst fic*: Some ethically-null folk mute Durandal with mental blocks so severe than even trying to write causes him massive headaches, with the idea that if he can't communicate verbally, his (barely-developed) ability to remotely write in terminals will be enhanced.
Unfortunately, that's not really the sort of thing that improves with practice, and even with mental blocks, Durandal's attempts at telepathy are borderline incomprehensible at best. Doubly unfortunately, the above ethically-null folks piss off before Vince can force them to undo the damage, leaving him to figure out the safest way to do that himself. It takes a few months.
And Durandal--well, he had enough of feeling helpless in any way when Strauss was conducting his "experiments".
* that someone else will have to write as I'm working on other stuff, but I'd be happy to bounce ideas
