I agree with you that Jordan's niceness was her downfall in both the real BB13 and the What If? one. She'd won before by being so nice, nobody could afford to take a chance to let her stay in the game too long. And I agree that Kalia could only have survived as a finals goat -- and Cassi had a nicer goat in Porsche. Anyway, here are the last four:

Shelly -- here Shelly didn't lose for backstabbing before she had to, she lost because she was too loyal to Jeff & Jordan for too long. She also was paired with a member of the Regulators in the early going and she unwisely revealed to him her true loyalties, thus she could never be a true newbie.

Adam -- Adam was strategic, funny and not a challenge threat. The challenge part was why he lasted for so long, but once he lost the second part of the final HOH competition and once Cassi won the final part, his strategic skills (such as they were) came back to haunt him.

Porsche -- the only thing she had going for her, like Radon, was her challenge prowess. She was better than Rachel at the social game but was just as bad at the strategic one. She managed to align with two people who could take her far but once there, her lack of strategic skills proved to be her doom just like in the real game.

Cassi -- a true triple threat. She was strategic (and might have been in the real game if she'd had more time), strong in challenges (and might have been one if she'd had more time in the real game as well), and totally nice. The main thing was to give her time and once she had it, she took control of the game and earned her victory.

That's it for the analyses of all the contestants. Hope you enjoyed them!
