So it has been bothering me that when Sawney and Bean died (in season 1) Erwin asked Eren "who do you think the enemy is?". I read that he is trying to fish out the mole in corps but I still don't fully understand why did he had to ask.

Later on Armin did explain the reason Erwin ask that quetion. Add on that if we replied to Erwin's question, we would know what Erwin is planning (trapping the female titan). I'm simply confused on how asking that question could help him figure out who is trustable and who isn't.
