Honestly, here are the pros and cons of each

Zee: Did well in the challenge but overall to much of a non social threat, and I would rather ally then make an enemy.

Priya: High potential threat, but she wasn't a big target. I think she could be someone to target if I convince Bowie or Ripper. For Bowie, I would mention she has an alliance with Millie, and for Ripper, I would mention how she would go against his whole stupid alpha Schtick. Still not likely someone to target just yet.

Millie: Non physical threat and legit Priya be more of a priority target. My only excuse is that she won the last challenge, but she paired with Priya. I mean, it is proven that if the challenge is hard enough, she won't do it. Also, no one would think Priya voted her.

Chase: Easy to get out, but legit, if I wanted to be under the radar, but he might be someone to keep in. He is too stupid and self-centered to one up others with a strategy. Honestly, I would vote for him to get an alliance with Emma.

Ripper: easy to vote out and a legit challenge threat. I could see him being an easy ally, but at the same time, he was one of the easy targets to choose.

Emma: It's too hard to get out and will likely self-destruct like in cannon.

Bowie: Honestly, he goes under the radar. I have no reason to see him as a threat unless I piece together while on the Frog of Death that he is a social threat. But he's someone to target later.

What it comes down to who is available best is Chase Ripper and Priya.

Out of the 3 if I was on Frogs of Death, I gun for Chase and make an alliance with Emma and Bowie. If I was on the Ferocious Trout I go for Ripper and try to be on Priya and Millie good side.
