The 100 Season 6 episode 5 will air on May 28, 2019. Episode 3 of the series was filled with weird mythology and political dynamics of the world. So, it is safe to say that the 4th episode was less exciting.
The 100 Season 6 Promo
The official synopsis is “Jordan investigates Sanctum; Octavia and Diyoza discover the threats of the new planet firsthand; Bellamy and Clarke butt heads.”
The promo of the 4th episode indicated that “someone is trying to kill us all.” And we see that they have to keep running in order to live. Because if “You stop, you die.”
Episode 3 gave us a deeper understanding of the Sanctum. They have a clear distinction based on blood purity. These people are also soft and they do not like to interfere in action much. They are good with science and basic community running skills. The children of Gabriel seem to be descendants of the patriarch of one of the four “prime” families that first came to colonize Alpha.
