This is a question of style. Personally, I see Von Genf's point. If your character's only encounter with the daimons was with an inhuman horror like Screamer, why on earth would you ever try to deal with them again? Why wouldn't you simply try to get as far away from them as possible?
It is commonly know, to those that are looking into the daimons, that they are all different. Even Brance, who has never dealt with a daimon personally, and has never specifically researched the daimons, knows that. So I wouldn't see any particular reason why a character wouldn't think "Woops.... that was the wrong one to talk to. Better try a different one...."
