Marauder's map prior to PoA? Why would they not have noticed that 
someone named Pettigrew was very often in the same place as their 
brother Ron, or at least, that someone they didn't know was hanging 
out in the Gryffindor common room and dormitories? I have looked at 
the FAQs on this topic, and feel like there must be more to this ...

Mary Ann:
Also how about when Professor Quirrell had Tom on his head. Why 
didn't they notice that he was always with him.
