There was a book that took place right after Order 66 that showed her going into hiding and eventually joining the rebellion.
I'm still of the mind set that we're going to see Order 66 and her and Rex's escape.
I have this heart sinking feeling that the last scene will be Ashoka hearing about the attack on the Jedi temple and breaking down because she believes that Anakin is dead along with her other friends.
Get ready for some heartbreak.
And yeah, that line is great, but her greatest line.
