I think the three of them really bring something unique to the house - it is a shame to lose any of them.
I hope it is Jason, as I think he relies on his homosexuality a little too much in the house to bring him sympathy votes (however this may be his reasoning for him staying).
David is just so open and honest - doesn't beat around the bush and people like that, I'm so glad he has outlasted Sandra - but it will be a fitting tribute to them both if they go out in the same week.
Priya - she is my everything, the lone wolf and the true player of this game. If she leaves I will be devastated, but unfortunately Australia decides not the minority that are Pristians!
