The hallway scene, when the mom begged him to tell her that her son was okay, and Danny said he couldn't do that... I thought I was going to have to bolt for the nearest tissue box.

I know I already said it, but a Danny/Lindsey scene would have cheapened the episode, and would have felt like a quick-fix IMO. As is, the episode has opened the door even wider for future Danny angst. And he does such wonderful angst!
