In re-reading OoP in the chapter Occlumency, when harry arrives at 
snape office, snape is useine DD penceive, and when harry ;eaves 
leaves he notices that snape is putting his  memerios back. My 
question is if while ss and hp are joined by the mind joining spell 
(the name escapes me) that voldermort could see into his mind too 
(snapes). This wouldnt be an issue if he wasnt trying to hide 
something from him (voldermort) like maybe that hes still acting like 
a DE? and he doesnt want voldermort to know that hes not? the fact 
that something is said about it usally means it implieas that it 
means somthing to the plot. 
It would be cool to hear y'all opinion on this matter.
