Okay. Today on my Xbox 360 version of Skyrim, I decided to go visit Delphine and Esbern to have some target practicing with my Crossbow, and to mess around really.. Anyways, I was shooting Delphine, who actually didn't did anything due to giving time in between shots... Well.. I eventually knocked her down onto her knees, which was to be expected. I decided to shoot her one more time and what surprised me is.. I did a ranged killcam on her and well.. Dead. After killing her and basicly staring at the body joy (I'm a Paarthurnax supporter) I decided to see if Esbern was killable. Went outside, found him training then slaughtered him quickly, which made me even happier.. Decided to dump his body in the river nearby..
So.. Do you think this was actually introduced or some sort of glitch, or what?
