> I do see your point, I just don't agree. We see that Marietta
tells on the DA for very specific reasons, because she let
herself be talked into doing something she didn't want to do,
and then became uncomfortable and conflicted by her loyalty to
her mother when she realized the scope of the DA's intentions
to subvert the Ministry.

Ceridwen:
Just throwing this out there for consideration:

In OotP, Percy writes a letter to Ron, warning him to distance 
himself from Harry and to trust Umbridge.  Since Percy and his family 
have had a falling-out at this point, and since Ron didn't care much 
for him to begin with, Ron ignores this advice.

Marietta, from all we know, which isn't much, may have had the same 
sort of letter from her mother.  Don't trust that Potter boy, he's 
gaga, and so's his headmaster.  Trust dear Dolores.  Go to her if 
there's a problem.  Marietta allows herself to get involved with the 
DA club because her best friend is in it.

Tangent: Another thing I've been thinking about - sure, Cho may just 
have joined the DA because Harry was in it, and maybe Marietta joined 
solely because of Cho.  But it's conceivable that one or both of 
these girls needed DADA for their future jobs, or were taking it 
because they like the subject.  We know that in year six, courses are 
no longer mandatory as they are in years 1-5.  Students take courses 
which are prerequisite for their future professions.  The O.W.L. 
exams aren't the only reason students might want to join the DA - 
students who need DADA for their professions might want practical 
experience as well.  So, it's possible that Cho and/or Marietta 
joined the club to further their practical studies in DADA.  /tangent.

So, Marietta is in the DA, learning practical applications of the 
theory being taught in her advanced DADA class, or just learning 
counter-spells against dark magic, and then it's suggested that they 
need to fight Ministry-approved Dementors.  Marietta may remember the 
letter her mother sent her about gaga Harry and dear Dolores, so, 
uncomfortable with what she sees going on in the DA, she does what 
her mother tells her to do and goes to Dolores.

Just a thought.  Percy's letter makes it clear that the Ministry is 
very down on Harry.  There's no reason to believe that he's the only 
Ministry employee who wrote such a warning to family at Hogwarts.
