The fate of the Vibe Tribe:
In the trailer we see Tristan getting closer to Benji & Hannah and Ivy telling Spencer he is the villain in their number which saddens him. Tristan did mention to Hannah they would be impacted by Zaid & Ivy leaving but if Tristan gets close to other players they might flip on Ivy if her behaviour proceeds. Maybe to protect her more than anything.
Tristan's vote will likely not matter though cus Spencer might start disliking Ivy and agree with Jade, Hannah & Benji to target her or Zaid. I think Zaid or Ivy will be the next Red elimination and I think it's possible Zaid gets voted out but Ivy quits the game to nulify his elimination.
I wanna also mention that Tristan joked in their audition that they will be too likable to vote out and I think it wil actually be the case, at least in the team phase.
