Yay! Someone mentioned the person in the corner! I was hoping someone would mistake it for Narcissa at first and then put it together that it was Severus after he came out of the pensieve. Thanks for the comment!
A memory of a memory would be very shady, but memory itself is shady and fluid, hence the need for a pensieve to make it all clear again. But it really wasn't doing him any good and hopefully he can move past this stage of his life and find someone to truly love him after the war is over. *shoves Harry in his direction*
