Puja:
I agree with Carol that the coward must be Karkaroff coz he fled when 
the scar burned and "one who has left forever" (Snape- coz we know he 
has redeemed himself to Dumbledore)
I am just wondering, if LV knows that Snape is the one who has left 
forever then what exactly is Snape doing for the Order? He could not 
be acting spy for Dumbledore coz that would be risking his life going 
near LV or any other death eaters. What do you think could be his 
work?
