Housemates Rob Stumvoll and Mariel Sorino drank too much and misbehaved during a tropical-themed party held for Finnish visitor Katlin Laas early this week on Pinoy Big Brother Double Up.

For the first time, the original House B housemates won the weekly task and were overwhelmed with lots of food and Finnish alcohol. Some of the housemates nearly forgot about their visitor. But thanks to Hermes Bautista, who developed an instant chemistry with Katlin, their guest didn't mind a one-on-one conversation and house tour.

Once again, the two houses are competing for next week's budget and it will be up to Katlin who will win or not. The housemates do not know that their weekly task is to show hospitality to Katlin. The blond foreigner spent time with the housemates in House A as they taught her how to sing "Maalaala mo Kaya" for her duet performance with Tom. House B also entertained her, led by Melay, who practiced folk dances like Maglalatik and Tinikling.

Meanwhile, Cathy Remperas is getting used to Finland's liberated culture after witnessing two men kiss each other in a party thrown by the Finnish Big Brother. Another pair even did something naughty beneath the sheets inside the house! Although shocked, Cathy handled everything well and has been well received by Finnish viewers.
