I hate to say this, but so far the sequence of events is identical to the previous couple. The guy arrives in the evening, goes to bed alone then leaves in the morning. The girl is out all night, comes home in the morning and goes to bed until the afternoon.
First there was nothing to take pictures of yet. The guy was briefly in the apartment, no one saw the girl yet. Second, you won't be able to see pictures anyway cause you are not a premium member. And finally, Karel is a man's name. This couple just like the previous occupants are either Polish or Chech
