Kjirstem:
I suspect Andromeda because whomever is appearing as Tonks seems
sincerely sad about Sirius' death.  That fits with Andromeda not
Narcissa.  I do wonder who is behind the imposter though, since it
seems to me that Narcissa has reason to want her own spy at Hogwarts
to check up on Draco and Snape.

Kjirstem:
Hmmm. Could be, I don't suppose Pettigrew has much to do with
Snape away at Hogwarts and Peter might be strongly affected by 
Sirius' death.

Kjirstem:
I do believe that Tonks loves Lupin, I just want to make that clear. 
But, what I want to know is how do you rationalize her behavior in 
the two situations I highlighted in my original post (132970) (Tonks
in the corridor by the Room of Req't and Tonks during the
battle)?  
I have trouble reconciling this explanation with her behavior in 
these two places.

introduced was that one's Patronis can change. 

Kjirstem:
I thought that was interesting too.  I also thought that the interplay
between Snape and Tonks when she dropped Harry off at the Hogwarts
gates was interesting.  Tonks would have preferred Hagrid to get the
message and this is clearly the first time Snape sees Tonks' new
Patronus.  Tonks' "
look of shock and anger" could have
been due to Snapes cutting remark that her Patronus looks weak but 
the shock part of that makes me wonder if there is something else. 
Perhaps a Polyjuiced!Tonks did not realize that her Patronus was
different, or that Snape would catch that fact?  (Or, hopefully, I am
feasting on red herring.)  I was worried by Lupin's handling of
Harry's question about the Patronus, he sounded like he had
reservations about his answer (pg 340, US  (deluxe, does it matter?)):

"Lupin took his time chewing his turkey and swallowing before
saying slowly, "Sometimes
a great shock
an emotional
upheaval
""

The interruptions to Lupin's reply only make me more suspicious,
which is a nasty habit I seem to be picking up.

I meant to add in my original post that I think Voldemort has every
reason to want an additional spy in the Order, if only to check up on
Snape.    

kjirstem - who is thinking about Tonks to avoid staying up to date on
the great Snape debate.
