As much as we love J.K. Rowling , there are a lot of things that dont make sense in the Harry Potter series.

For example, theres no discussion of kids taking subjects like math and science. If Muggles have to suffer through algebra, wizard kids should, too. And why didnt Voldemort just break Harry Potters glasses or something? So many plot holes. So little time.

Beyond these little annoyances, one glaring plot hole remains the chosen one: Why didnt Fred and George notice Peter Pettigrew sleeping in Rons bed on the Marauders Map?

The Weasley twins had the map , which is able to show the location of each person in Hogwarts, for years before they gave it to Harry. During all that time, wouldnt they have noticed Ron hanging out with a guy named Peter Pettigrew, who was really an Animagus disguised as Rons rat, Scabbers?

We first posed the question to Rupert Grint , who said he didnt know for sure but added, Thats a good point, after we suggested that Ron was technically going to bed with Pettigrew every night.

Thankfully, Oliver Phelps, who played George in the movies, came to the rescue.
