Found this via... some rec. In some comment in someone's journal, I think. Inkbug's, maybe? Not sure. Anyway.

I just have to commend you for this - for the pain, and the images, and the fact that I've never seen anyone get the voices of the twins so perfect. Not one line seemes out-of-place, not one word. At first it seems like Murphy and Connor are so far apart in their thoughts, but then they progress until at the end their minds are back together, like one person almost. Aaaand I'm not making any sense. Add one more "guh" to the list.

Amazing and painful and beautiful and thank you for writing this, no matter why you did it.
