Ok...it now seems, that Ebba and Rickard didn't walk. Rickard was forced out of the house, and also got psychiatric counceling right after. He just basically got a bit psychotic. Even Ebba didn't really get him anymore...or at least that's what she says.
So...a week gone there's already been 2 HMs who were going to walk (Katerina and Sanna) and 1 HM who lost it. And was either removed or her girlfriend decided to walk...this is unclear. But eiher way, doesn't really matter. They were looking for people, who can create controversy. Seems, like they nailed it. A bit early to say though.
