Last night's revelations left chaos in all tribes in the primitive world. The facts about the trials from the Beast God were all sent for everyone to experience as a dream. Thankfully there are only two trials but in spite of it, no one could become happy about it. First, winter had already arrived. According to the timeline, that hellish winter with cruel snowstorms and hail would be coming soon. They don't have enough time to prepare. They don't even know when the exact time the snowstorm would land.
Second, this is a problem from the other tribes, no one of them knows who that pair is nor which tribe they've come from. They had to blindly guess which of the big tribes would know the identities of the chosen ones.
The Lune Tribe has no problem with this as the chosen pair were their own tribesmen.
