Would it make sense for Quirrell to be Sirius Black polyjuiced? He might actually just be polyjuiced; that's why he's been so intent on helping Harry, because he's SB. He's able to do wandless magic because once he became an animagus he figured out that other wandless magic was also possible, or at least how to do this.
