Spoiler for ep 5, late speculation:

Episode 7 involves Battler setting up a careful mix of red/blue/gold truths that trap Erika into being the culprit in the way she trapped Natsuhi into being the culprit in episode 5. The resulting contradiction gets her destroyed by Dlanor. With her removed, Beatrice is revived. Battler relinquishes his title as game master back to Beatrice and takes up the last game as player.
