I want freddie to go because
 

who will Bea set her sights on next. Yes Lisa will be smug but Bea might be cautious of setting her sights on destroying Marcus after last night - so will she turn on Lisa which will be brilliant because they have all seen Bea at work now and if she goes down this route she will be totally exposed.
If Marcus goes Bea will just continue to be evil to Freddie because she knows hes weak in these situations and she knows Lisa charlie etc will side with her - this in my eyes does not make good telly I found it quite distressing the other night what she did to Freddie.
Unfortunately if one HAS to go it should be Freddie - also if Freddie goes this may make the others think Marcus is really liked - will there attitude towards him change
