My first "what if" is the whole Allison/Joshuah/Sheila drama that went on. I think that whole situation could've been avoided if Jen and Parker (they winning Power Couple at the time) ignored Jacob & Sharon's mistakes and evicted Adam & Sheila instead. Now it had only been three days and Allison and Sheila never got any alone time or any time to get to know each other. Now this is my theory, when Neil left, Joshuah was more likely to have chosen Sheila to return over Adam. Now even if Sheila and Allison got along after nominations, Sheila wouldn't have come up with that lesbian story, because she knew that would offend her partner and put another target on her back, so there wouldn't be any of that drama between Joshuah & Allison. That's how it could've went down. And since Adam won the whole game, the fight for the winner would've been up in the air and anyone could've won.
Another "what if" is when Jen/Parker & Allison/Ryan were nominated. That could've easily been avoided if Jen/Parker had kept their mouth shut. The houseguests were right, Allison is manipulative. Because she threatened to spill the beans when she really had no intent to do so and actually got Jen and Parker to do it for her which resulted in their eviction, because Allison was aware of Jen's cockiness and she knew that with Jen gone Ryan would be fully focused on the game.
