imthruthelookinglass now:  He could also have left proof of his 
agreement with Dumbledore stored inside the Pensieve as proof of his 
actions as a request of Dumbledore and his loyalty to OOTP.  However, 
this information could also fall into the hands of the DE.  So it is a 
question as to whether or not he would take the risk.
