Can anyone tell me if she's reading an event that happens later in
the HBP (like the Malfoy situation) or something else? Like I said
it's a bit of a trivial question but it's been really bugging me. I
cant help feeling I'm missing the obvious.

Janelle: I tend to read this section as a warning that we should 
take Trelawny more seriously than we have in the past.  Harry, "a 
dark young man" is standing, hidden, listening to Trelawny "the 
questioner" make these predictions.  I think it's interesting that 
she seems to get something right, if she is in fact referring to the 
fact that Harry is there and that he dislikes her, and then she just 
writes it off saying, "that can't be right" or something to that 
effect.  I always read this passage as a hint that we should pay 
more attention to the things that Trelawney says because she tends 
to be right more often than we are originally led to believe.  

As I reread what I wrote above I realized that when she draws the 
Knave of Spades she ends up referring to something happening right 
at that moment, Harry's presence.  Could it be that the other cards, 
the two, seven, and ten of spades are also representing something 
that is happening right then or that happened immediately before 
this moment?  "Conflict", "an ill omen", and "violence".  I really 
wish I had my books with me so I could re-read this chapter and find 
out what happens around that same time.  I'd also go back and read 
the chapter of PoA where Harry looks at that book about bad omens, 
you know, the one wiht the Grim on the cover.  There could be some 
sort of interesting connection there.

Also, could the knave of spades, the card representing Harry, be 
significant in some way?
