Stalas experiences the most unpleasant epiphany of his life.

He recognizes the body from all the way across the cavern, starts towards it, and then halts in his tracks. "Gorim - I can't go near him, do you understand? Go - be careful - tell me what you can - you two, hang back with me," he says to the scouts. "Whoever did this must still be nearby, and ancestors only know what else they're planning. It can't have been darkspawn. Darkspawn would still be here."

Not to mention that at this point in time, the list of people Stalas trusts is extremely short.
