I don't see it as scientific vs supernatural. At all.

The appearance of ghostly beings can involve both scientific and supernatural phenomena. A solid, mute, lookalike girl to me, means:

a) She's ignoring them
b) She's had a memory loss (or developed a multiple personality disorder)
c) She's a look-alike. An actual "clone" fits here.

I think the correct thing to say in this case would be:
Still, it doesn't feel as mysterious to me anymore, though she did disappear on them.
Isn't that implied? Something as subjective as "it doesn't feel as mysterious anymore" of course can't be shouldn't be taken as fact.
