Sorry, got mixed up when updating the John/Cam fic list and posted this on the wrong story! So here it is in the right place, where I'm sure it will make much more sense:

Oh wow. This is wonderful. I love the fact that Cam can't, in fact make everything better, because John's too damaged at this point for this work, but he tries his best and manages to improve things a little. Though maybe not enough, from John's thoughts at the end. The whole thing is really quite heartbreaking.

The description of Sam's reaction on finding out what happened is excellent, and exactly what should happen. The only thing more satisfying would have been seeing the confrontation. (I also love the way Cam still clings to a little bit of his hero worship when it comes to Daniel, even as he hates himself for it, knowing what Daniel can be like.)

Beautiful work!
