Now that I think about it, that arrest scene is a bit odd. After millions of years she must know that her appearance doesn't change and that this is very unusual for normal humans. Why is she just waiting around to be caught?
Probably perspective. When you're durable enough to sit under the ocean for millions of years, walk on top of a glacier, take an aurochs to the face, and take a spear to the gut, being arrested probably isn't that much of a hindrance.
It'd be like you or I being told to go and sit in a corner for 60 seconds, if that.
Well you look into the water and the fish are dead
You close your eyes and all you see is red
Now you're all tied up inside your head
And I already forgot everything you said.
