After the female housemates performed the "Burning of the Witch" traditional dance, Big brother announced that the winter season inside his house is already over. Big brother then had a conversation with Seichi and Eting separately, giving them a challenge to do the 9th weekly Kontra Battle. Big brother challenged Seichi and Eting to discover the Big secret of Anthony and David. On the other hand, Anthony and David are also given a task not to reveal their secret especially having a three stars and a sun tattoo at their left arm. Anthony and David's mother are half Filipino but they must pretend to be pure Czech's national. Yesterday, Eting and Seichi started their secret Kontra battle task. Seichi had his chance being alone inside the male's bedroom when the other housemates are busy at the dining room. With this in mind, what are the things that Eting and Seichi discover towards Anthony and David?
