Do Lewis&Marnie really care about each other? Does Bear have a Heart? Just two examples of Questions that HMs could be asked

Do you make it up as you go along? eg Let people give killer noms then two days later give nominated HMs a chance to remove the nom - POINTLESS.

Oh sorry - thought you meant give BB a lie detector (Duh, well it is 7 in the morning!)

They have done it before during BB7 Dermot hosted BB Big Brain on BB7, evicted HM's were subjected to lie detector tests. Now that was a series.
