In the movie, there is a scene where Elizabeth enters the forbidden room (this is the second time around). This time she ends up waking the next clone. The next clone wakes up with this confidence about herself. Walks around and finds Elizabeth sleeping.

So,

1. How is Elizabeth deep in sleep that quick?

2. How is this clone so sure of herself right outside the tank but in the end she seems to be a confused wreck with a gun.

3. What is the significance of the clone trying to take off the clothes from Elizabeth? She wakes up with her pyjamas pulled down.
