SSSusan:
Erm... can I ask how this is canon?

Per DD, in the Weasleys' broomshed:

"Yes," said Harry again.  "And now everyone knows that I'm the one--"

"No, they do not," interrupted Dumbledore.  "There are only two 
people in the whole world who know the full contents of the prophecy 
made about you and Lord Voldemort, and they are both standing in this 
smelly, spidery broom shed."
[HBP, p. 78, US edition]

So how do we know Snape has known all along?
