Once the last word has been acquired by defeating the hive enemy in a showdown, the drifter says something along the lines of: "don't trust the guy who gave you that gun" (as he is the guy that killed his friend)..... but, nobody gave me the gun. A hive enemy dropped the thing after trying to kill me. I'm assuming he is referring to Shin Malphur... but it wasn't Shin, it was a hive enemy that had the gun. Did I miss something or is this merely another area of the game where bungie decided to leave out the actual story and lore aspect of the quest?
