I have a feeling her and Jake will be safe tonight. Her bizarre ploy for camera time has probably netted her a few save votes, and votes for Jake will also work in her favor.
The positive attention being focused on David recently should also help to keep him and Sandra safe, though I think the whole shaving of the beard "event" was designed to bolster his support, which may mean he and Sandra have the least votes.
Ultimately though, I feel like it's going to be Travis and Cat on the fewest votes to save. The teen crowd have been too busy saving Lisa and Skye this week to even care for Travis. Without Ryan as his partner, there is less compulsion to save him. I feel like if they choose to save anybody now, it will be Jake, though most people are probably smart enough to realize that Jake will be safe no matter which pair is voted last. Cat has been given the silent edit this week, and has been very much a peripheral character, so the individual support for her is going to be quite low. It will all depend on how much individual support Travis has. He's a talking point so it could be high, but he's not that likable so I think it won't be enough.
A week ago, I would have said Cat would be the evictee of choice for the housemates, but after yesterday, I can't be so sure.
This one is tough to call, so we'll just have to see what happens.
