Huh, I didn't really realize the thing about the surviving victims -- I was too busy d'awwwing over the way Reid interacted with her.

And then, after that, Rossi comes over, and says, "Well done, Agent Reid." That's twofold, too -- wait, more like threefold -- because it shows Reid's development over the series (Gideon had always introduced him as Dr. Reid so people would take him seriously), it shows a subtle, quiet difference between Rossi and Gideon, and Reid admired Rossi so much in the beginning -- It's just a fantastic set of scenes, fantastic episode in general.
