did it, or what she thought would  happen. Please note, she 
didn't seem to have warned he best friend Cho. Cho was  one of 
the attendees who were nearly caught by Umbridge and the IS. <

Pippin:
Actually, I think we do have some clues to what triggered the 
betrayal, though Rowling doesn't make it obvious. First we have 
the story of Regulus, who "got in so far, panicked about what he 
was being asked to do and tried to back out." That sounds like it 
might apply to Marietta. We also have Fudge's statement in GoF 
that "half of us only feel safe in our beds at night because the 
dementors are standing guard at Azkaban."

Did Harry do something that would have caused Marietta to 
panic? Perhaps. We know they had started learning the patronus 
spell. I don't think Harry thought clearly enough about the 
implications of teaching it. As far as he's concerned it's just a 
class treat.  It's far beyond ordinary wizarding levels--they don't 
need to know it for their OWLs. In his mind, he's not training 
people to resist dementors, either, because he knows what kind 
of training it really takes to do it. He's also firmly convinced that 
the dementors are outside Ministry control and may be already 
working for Voldemort

 But to someone who believed that the dementors were under 
ministry control, and who didn't realize how much magic it would 
take to actually fight them, being part of "Dumbledore's Army" 
and training to  use the patronus spell would look pretty 
bad, especially after the Azkaban break out. It'd be like if your 
self-defense group started training with armor-piercing 
bullets. You'd wonder if someone wasn't planning  to fight cops.
