Will Seamus be the traitor?

Hey, thought I'd bring up something I'd been mulling over for a 
while.  There's obviously a lot of theories about whether Ron will 
betray Harry or not.  What if Seamus becomes the traitor?  When 
Seamus Finnegan is about to be sorted in SS, the Sorting Hat took a 
long time to figure him out.  We know that the Hat took a long time 
to sort Neville and I figure that's because he may have borderline 
bravery (i.e. does he actually belong in Hufflepuff, he is good at 
Herbology, etc).  Where do you think the Sorting Hat was thinking 
about putting Seamus instead of Gryffindor?  Any of the other houses 
is a possibility, but my hunch is that the Hat was thinking about 
putting him in Slytherin.  The reason for this is that I believe JKR 
put that in for a specific reason which will be revealed in time; I 
don't believe that there would be any big story if the Sorting Hat 
was deciding between Gryffindor and Hufflepuff or Ravenclaw.  
However, my hunch is that the Sorting Hat was choosing between 
Gryffindor and Slytherin, ended up putting Seamus in Gryffindor, but 
he will eventually end up betraying Gryffindor and Harry at some 
point.  No other cannon evidence at all to support this except the 
fact that the Sorting Hat took a while to sort him, but I just don't 
see why JKR would include that tidbit if it wouldn't be important 
later- and I don't see why it would be important if the Hat was 
deciding vs. Hufflepuff or Ravenclaw.  Any thoughts?
