You know, I've heard people say that before -- and I could totally see it when Laura Benanti played her in the TV version, even though that was the Broadway show version of the character, who, as nuranar says, has worse motivations. Of course it didn't hurt that Benanti was a vastly better actress than Carrie Underwood!! She gave the character some depth and poignancy -- not to mention killer snarking skills. :-)

I still don't see it in the movie, though. For some reason, in the movie, she gives off a very insincere vibe to me. I don't know why exactly. Just an "eye of the beholder" thing, perhaps.

However, I do think her parting line to the Captain is very gracious and kind -- she's giving him her blessing to go to Maria. (And I love his startled reaction. Like the WHOLE WORLD couldn't see what was going on with you, sweetie. :-D )

And now I think I need to go find me a "Sound of Music" icon or two! :-)
