Yes, the infamous "Gray 17 is Missing." To me, the saving graces for this episode, aside from the fighting pike duel, were the real zingers of lines near the end:
Marcus's whole speech about who the Rangers are: "We walk in the dark places no others will enter..."
Garibaldi's line about having a really bad day.
Neroon tells Marcus that he's learned a lesson, and Marcus asks if he can find a less painful method of learning in the future. Neroon walks off laughing, the first time he even so much as cracks a smile, I believe... and rather poignantly setting up his final lesson, dying for Delenn.
