Just got over here from a rec in tw_classic. Don't know how I missed it first time round, but am incredibly glad to have caught up. This is amazingly powerful and chilling. That sequence from flowers to pixelation to C++ to gray was just... gah! I don't know how to describe it. Pictures of a mind breaking down. And it fits the Tosh we saw so well - often broken, but with flashes of what she might have been before UNIT.
