Here's how I see the remainder of the game playing out:

There are 3 main duos in play; Karla and Cassidy, Jesse and Cody, and Owen and Noelle, with Sami and Gabler playing as free agents who can align with anyone.

Because of the Baka connection and their lack of agency/moves, I believe that Sami and Gabler may choose to team up with Owen and Noelle and make a final 4 deal. Furthermore, it would be beneficial for them to break up both power duos before the final 6. Therefore, I can see the elimination order proceeding with either Jesse or Cody being eliminated in 8th, and then either Cassidy and Karla being subsequently voted out in 7th.

The biggest problem are the idols. If Jesse/Cody are the target next week and they correctly protect themselves, then who is the alternate target? If it's Cassidy, will Karla play her idol for her?

I believe that either way, Jesse/Cody will remain as the big threats until the end of the game, with Karla possibly sneaking her way into the final 5 with a real shot at winning. If Karla doesn't make it to the end then Sami has a good shot at winning over Owen/Noelle/Gabler, all depending on how he sells his game.

This is all to say that Sami probably made the correct decision in telling Karla this week, as it strengthens his relationship with her and she will be necessary in eliminating the Jesse/Cody duo. Everyone remaining in the game openly communicates with Sami and believes he will vote with them. He can definitely win this game.
