in Snape about Sirius, which you are supposing he would not, Snape 
would not be aware that Harry was corresponding with him in GoF, and 
that Sirius lived in the vicinity of Hogsmeade for a time and was 
visited by Harry.

meetings and did not socialize at all. Nor did he and Harry ever 
discuss Sirius. Snape could *speculate*, naturally. So could Peter, 
for that matter.

Dana:
You are forgetting two occasions where Snape witnessed the 
relationship between Harry and Sirius himself. 
One at the end of GoF when the Sirius in his animagus form set next 
to Harry's growling at Fudge for calling Harry a liar and the second 
is in the kitchen scene in OotP.
