The idea kind of ran away with itself - it's three characters, brothers, who have been made unable to speak, so there's now an element of their sibling connection on a subconscious level to the whole thing. They play a large, if not main, role in my story, so it's both fun and really quite tricky to see how they fit with different speaking characters.
What started out as a small element of half a chapter has now become quite major - for example, they witness the murder of a relative, whilst it is expected they do not react to it, I still need to convey emotion - albeit tightly controlled. So micro-expressions are essential here.
I haven't had any time to really sit down and write recently, because of work, but after this week I'm hoping to get some more done. Because I really want to add some humanity to these characters, even though they are the bad guys in my story. Or, at least, three of the bad guys.
I'm trying to create a level of complexity and depth that kinda makes someone stop and think about how they judge a character and what makes them pick a favourite/favourites to champion, even if it's usually not a conscious decision. No one in my story is outright good or bad - I guess I got sick of reading books that sort of forced the reader to champion so and so, when in reality that character wasn't all that anyway.
I dunno. Prolly being overly ambitious, but why not?
