This scene is more important than I originally thought. Does Clarissa recognize the body immediately? Whose body is it? If she is going to take Pali's place on the Sweep Team there needs to only be one spot open. It could be Telam. Or only once it's cleaned and on the operating table? Also, the Ergon is there. He was led to this spot and waits near the body. He kills the fleeing cultist, which allows the patrol to catch up and then Clarissa fights him. He recognizes her from his dream and surrenders. He gets blackjacked by another patrol member, but only after he says he was sent to find her. Later, she tries to get in to see him, but there are strict rules about prisoners, especially Ergon: no visitors. If she recognizes the body of the Census Agent, perhaps she whispers his name or blurts it out, causing a significant response from the First Servant, who has come to see the body for himself and consult with Simon.
This is the first time we see Clarissa go out on a patrol, but is not her first patrol. The armor and weapons to me seem like a hodgepodge of whatever the Servants can scrounge up. The elite guards have great equipment, but there are few of them. It is not DIY like in Fallout, it is eclectic though. Perhaps she can show her combat prowess here against some random other cultists. Mix this with her discovery of the body and her link to discovering the need for pure tralaticon and it makes her seems connected with success in the cult.
This is where Clarissa finds the body of TKNAME from Pali's team. She recognizes him, but does not know him. A certain amount of time needs to pass between the lab scene and this one as she gets used to cult life. She also has forgotten her mission and is loyal to the Pool. This body reminds her of that and the realization and fills her with guilt at this unconfessed sin. Does she consider herself a threat to the Pool now? A weak link? This is good- that would really rattle Clarissa, the feeling of being the weak link. This can filter back to other conversations.
