It was a bit odd. They came came home and went into the bathroom to freshen up (they were looking at their sunburn marks), then she went into the bedroom to put on her little outfit. She went to the kitchen and within two minutes they were at it. It did seem a bit planned.
He threatened that he was going to call the cops several times. She kept saying that he's a liar and that she can't trust him. There was also discussion about something on his phone (call logs or texts, that she found).
Not much. She did take a shower (I guess it was a shower, she didn't use soap)...took everything off except her bra. Later on she went into the WC with no cameras to change the wet bra. Very odd.
I'm pretty sure it's the main bathroom for the apartment, I heard Marcelo running water in there. The bathroom with the cameras is the master bedroom bath. Without a main bathroom, guests would have to go through the bedroom to get to the bathroom, which is not typically done.
