As I posted in an earlier thread, Travis is streets ahead of the others and pretty much has the game won 6 weeks out from the finish. Mavroidakis knows this and knows a competitive finish will garner better storylines and higher ratings.
That's why he wants one or both of Trav and Baby Aish...
She has sex appeal. And her vulnerability and sluttiness might also appeal to some.
Cat is very far from unattractive.
Lawson on the other hand .... that big round Andrew Gaze head. What's the appeal there!
I think Marina is quite sexy but god knows why BB would put an intruder in there who already has a partner on the outside. Just dumb.
The worst ever intruder was that hyper sensitive bear gay guy Nathan from last year.
