VIOLA: Character interpretation/objectives

Since being cast as Viola I have been researching her and looking into her objectives and roles in the play and have developed my own personal interpretation of her as a character and as a person.
I feel Viola is a very strong woman and has a lot of guts, she creates a role for herself "Cezario" and plays along with it and fools everyone, this is very brave of her and she knows what to do to get what she wants. She is in a way two different people, as she is playing herself and Cezario, so for me I am going to have to understand how to play two different roles in the play as in one of my scenes she is acting as Cezario, and in my other scene she begins as Cezario, but is unravelled as Viola as she comes face to face with her twin brother Sebastian. 

I feel Viola is quite ruthless, in the sense that she is does not care that she is tricking everyone into believing she is a young man, and she is very good at it. And when she is unmasked, Viola does not react in a very defensive way, she never really explains herself to anyone, and I like that about her. She is a strong character and is very cheeky and humorous. She brings humour into the play, along with Sir Toby and Andrew Agucheek.

Viola is very humorous, particularly with Olivia. The two females have a rapport together, they seem to click from the word go, but this bond is tainted as Olivia believes Viola to be her male alter ego, Cezario. In my scene with Sav, between Olivia and Viola, I have learned a lot about Viola and her objectives. 
Viola is very cheeky and flirtatious in her first scene with Olivia, when watching the film Twelfth Night, I do begin to wonder at points if Viola is meaning to flirt with Olivia, but I do not think she is intentionally, as she is doing it for Orsino, her master. HOWEVER, it does become apparent that Viola is in LOVE with Orsino, so I possibly feel there is an agenda in this scene, as Viola does not want Olivia to be interested in Orsino,as she is. But it is clear in my scene that Olivia is not interested in Orsino at all. Watching the scene a few times has helped me with my character interpretation and development as Viola is so playful and coy in this scene, and it is going to be really exciting for me to play such a different character compared to other characters I have played in college shows and things I have done outside of college. As I have always be cast as strong, serious and grounded(or nasty) WOMEN! So being cast as Viola is definitely a healthy challenge for me, and she is so different to what you would expect. Since rehearsing my scenes as Viola I have noticed a change in my acting,I feel much more comfortable with comical acting and I feel a lot more in tune with my  body. Learning TENSION exercises from Stanislavski has helped me develop my role as Viola as I feel so much more in tune with my body and I have let go of my mind, which was always a struggle for me. I really like Viola and I feel she has strong objectives,and does things for the right reasons, probably not the right things but she has a good heart and she is a feisty woman who knows what she wants.
