Episode 4 is the fourth episode of Britannia. It will air in January 2018 on Sky Atlantic and was released online on 18th January.
King Pellanor disowns Kerra and leaves her life in the hands of the Druids. But the gods' judgment is not what he expected.
King Pellenor becomes aware of Kerra's negotiations with the Roman Empire. Edged on by Amena's manipulations, Pellenor declares that Kerra has betrayed the Cantii tribe. Imprisoning her, Pellenor sends her to the Druids, the voices of the gods, for judgment, which they both know means death for Kerra. The Druids had previously judged Kerra's mother and flayed her alive.
Kerra releases Phelan from his oath to protect her, and is visited by Lindon, a Gallic warrior and another of Amena's husbands. Kerra and Lindon are also more than just friends. Kerra is taken for judgment before the Druids and meets Veran.
