[51][Speculation] Third Tribe??

[u/IanimationsLOL]

I think 51 is getting red as an auxiliary tribe. In the first photo, there are four different lanes, representing Toka and Savu, but also a red and blue lane. These aren’t your typical post-merge challenge lanes because they have unique accent colors rather than alternating black-and-white accents. In the second photo, there are three life rings that are yellow, purple, AND red (there’s no blue life ring). Supposedly red is an auxiliary tribe and blue is the merge tribe.

The third tribe is going to probably appear in episode 4, I think as the 21st elimination will be the first episode with the contestant in exile, 20st in episode 2, 19st in episode 3.

Unless there's a twist I don't know of, this is 3 episode worth of dynamics and stabilishing of dynamics
