4x10 Graphic might interest you? Nothing major like The Fifth Man, but I believe there's a nice but small scene (after the danger) where Charlie expresses his worries? The aftermath of The Fifth Man (5x21 and the first few episodes of season 6) has some worry elements. That's from the top of my head, so I hope it's helpful.

Edit: I know there's a lot of emotional stuff throughout but It's hard to remember the eppy titles.
