of the ones listed, my favorite from recent seasons is horatio's pain in 10.01. he struggled so bravely and still managed to bring the villians down despite his wounds, such an excellent show of horatio's dedication. and david played it beautifully. from earlier seasons, i vote for the entire team walking down the beach. i love seeing them all together and smiling, especially horatio. we needed at least an end like this on the series finale.
