Don't know, why Gurkan and Roza were still immune. But I do know, that Niklas is not going anywhere. It's really a competition between the girls...my guts says it's Sanna who will be evicted this week. And also I've been kinda following what is being discussed on the official Facebook page. But still...it's going to be close between Katerina and Sanna. I really don't think Nicky (as they call Niklas) has any worry. I also know, that Gurkan and Roza won't be immune anymore. And quite a few are already hoping, that Roza would be evicted next week.
Also...it seems Simon is building quite a fanbase. He might be the winner this season. Along with Gurkan. For some reason Gurkan also has a huge fanbase. Can't really even see beyond these two competing for the win.
Of course a lot can happen before the season is over. At the momen it seems, that the winner is going to be a guy though. The girls are kinda boring. Sara could go far, she's kinda under the radar. I don't see her getting nominated anytime soon. And I can't see her walking or being ejected for any reason either.
