I get the distinct impression that BB is simply giving the HM's time to get used to each other, findout likes/dislikes and all that - lulling them into a false sense of security...

I am expecting the evil side of BB to surface without any warning at all. Remember the divide? There was no warning there either....

I'm enjoying it already anyway!

So am I, it's reminding me of the first show in some ways. I still wouldn't say no to more evil surfacing without warning though.
