I don't agree that either Pat or Fatima are less entertaining as the other. They both add something to the show and it's a shame one has to go because I can think of a few of them in there who aren't as 'entertaining' as Pat and Fatima have been during the show so far.
I think if it's a task based on determination or strength Fatima will win, though she may want to go home to see her family. However the look on her face when she found out she was bottom two shows, to me, that she isn't happy to be bottom two!
