If she could choose what form she appears in, why would she have been "found out" in the late 19th/early 20th century?
She can decide what she looks like, but at some point she's sort of stuck. She decides to look like a human. Something happens to her that should kill a human that bounces off of her. How does changing shape deal with that after the fact?
NOTE: I don't actually subscribe to the appearance-changing theory.
