Ep 15. The Ballad of Breaking Up

In a devastated city, Stig's group is driven into the subway by the Refles' new mecha, the Gamo and sealed inside a small section. While buried alive, tensions brew within the group as they struggle to stay alive at the same time as they are coping with Mint's decision to stay with the tribal people. If they get out alive, Rey and Houquet boast of leaving the group for good.
