During the cursed tribe quest, when malacath was just about to be summoned a blood dragon attacked. With mjoll and the whole tribe the dragon was easy to take down but I was surprised when yamarz jumped on its head and performed the dragon execution move. I have never seen an npc do that move and thought only the player could do that. Has anyone else seen an NPC use a finishing move on a dragon.

I guess Yamarz isn't that much of a weakling after all. Funny how he complained about killing having to kill a giant after killing a dragon.

lol,
but yeah NPC's can do Kill cams on Dragons too, I've had Derkeethus kill a Dragon like that as well. and even a Guard in falkreath did one o.o

No dragons but I watched Lydia decapitate a forsworn

I once saw a random farmer do the same.
