This scene destroys me every time, but one incredible detail that I haven't seen anybody mention is the position of the bedding.
In the first shot, when Edwin arrives, we can see that Charles has taken one mattress and one blanket to huddle in the corner with them.
In the final shot, all of the bedding has been rearranged on the floor to make Charles' little blanket nest as Edwin reads to him.
But Charles spends the entirety of these scenes growing weaker with each passing shot. He's sitting upright and shivering, then leaning against the shelves and shivering, then leaning hard on a table and coughing as the internal damage starts to catch up to him, then leaning much harder on the shelves after the shivering has stopped (a bad sign when someone is hypothermic), then leaning so far down he's near reclined, then finally lying flat on the floor amidst the bedding.
My point is, by the time that final scene comes around, Charles doesn't have the strength left to have moved the bedding for himself anymore.
That was Edwin. Edwin sat with this dying boy, and brought him light, and made him laugh. And when the end was near, he made him a blanket nest on the floor, so that he could die in comfort while someone read him off to sleep.
