I noticed while watching the trailer for house of wolves a couple times that the fallen captain that you see walking away at the very end was holding some sort of flame, I also noticed earlier in the trailer that one of he awoken soldiers had a hole burnt into her chest. This reminded me back to all of the videos on DLC exotics coming in house of wolves, particularly one shotgun by the name of "Lord of Wolves" I remembered that it did lingering fire damage upon landing rapid hits which made me think that it had to be the same one. When I looked closer and closer at that captains hand I realized that it looked like he was actually holding something and that something looked very similar to the lord of wolves exotic shotgun. Boom. Life hack.
