LOL, exactly.  I had to go back (sad) and relook at the old Bree vids where she went to the order.  They do seem to keep their distance so at least it's consistent!!   I think that the Helpers are able to get close to them, but perhaps the higher up the order you go the more dangerous it is.  However, if that's the case, why send someone who is vulnerable.  Hmm.  Ponders.
