She has in the last days also been hidden in the hidden/washer room upstairs for a long time too, even closed the door. She mostly goes on the balcony when she talks on the phone, so she doesn't reveal anything. And is a little paranoid about it too, since she often turns the TV up to drown out any sound from the balcony.
The upstairs is when she's on the PC, and most likely skypes or something like that. It's where she charges it.
But at least she do show stuff when she's alone. The other two, who is out, and on the way out, never does anything.
