Me, Del : 

Leo, the Lion ? You're sure ?? That doesn't fit ! Regulus was in with 
LV, how can his star belong with Gryffindor ? Could it be that Sirius 
was wrong all the way about his brother ? Maybe Regulus was in the 
original Order, a mole in LV's camp working for DD ? But DD would 
have told him...

Del, who obviously loves the idea of moles all over the place ;-) 
(and who called her cats Eclipse, Andromeda, Orion and Vega, but that 
was before OoP and is perfectly OT...)
