Demetra:
I'm going to make myself unpopular, but here's my take on this.
I think that Sirius and James were the tight-knit friends of the 
group and the major mischief-makers.  McGonnagall compares them to 
Fred and George, and Sirius admits to Harry that he and James were 
often in detention.  What is it about studious, nose in his book 
Lupin that would make James & Sirius take notice?  I think that the 
fact that Lupin is a werewolf and that they saw the potential for  
fun cavorting with a werewolf was what made them want to befriend 
Lupin -not that they befriended him first, then accepted him being a 
werewolf.  
So, why does Sirius think that Lupin is the spy?  Well, he knows 
Lupin is a werewolf.  I think that in a time of war, where members 
of the order are being picked off one by one and his best friend is 
forced into hiding, Sirius reverts back to his upbringing and the 
WW's general prejudice against werewolves.  He suspects the 
known 'dark creature'.  It is just like Ron (who has known Lupin as 
a kind, friendly teacher for an entire school year) reacts in the 
Shreiking Shack by telling Lupin "get away from me, werewolf".  Or 
just like Snape reverts to calling Lily a "mudblood" when he is 
being humiliated.  It's an ugly part of human nature that in times 
of stress the old prejudices rear their ugly heads. 
Why, then, does Lupin suspect Sirius?  Well, for one thing, he knows 
that Sirius used him in the prank episode, with total disregard for 
what could have happened to Lupin.  Is it so hard to imagine why 
Lupin would believe that Sirius could have put another friend in 
harm's way?
