[There's a
squeak (the one at 0:12-0:13 or 1:07-1:08 if you like).
The clattering of a PDA hitting the wooden floor.
Running footsteps. Pointedly away from the PDA.
Not to mention the rustle of something moving past it. (Probably her hair)
And quite possibly a door opening and slamming shut.
What may have caused this? Someone might have seen their own cadaver.]
