Gross! You know where that beak has been! Inside someone's entrails!
Yeah, but watch how people interact with their dogs, and we know where those tongues have been, too!
Desdaemone feels the same way about her clannfear, Lucy. Clannfear summons are special. They go off seeking out threats to their conjurer, and then, when all is well, they come back and practically beg for praise.
They also seem to draw the AI's attention quicker than some summons. On the arrow thing, I've found that if Desdaemone calls Lucy immediately upon encountering an archer, there's no need for invisibility, dodging, arrow removal from oneself, etc. Lucy gets the archer's full attention.
