S04E03: A Rose at Summer's End

While commemorating a cemetery to the Imperial war fleet, an assassination attempt is made on Reinhard. It is revealed that the assassin's family was killed in the nuclear strike on Westerland during the Lippstadt conflict. Reinhard is shaken to the core by his own guilt and inaction during that time. Reinhard asks Hildegard to spend the night with him. The next morning Hildegard goes home to her estate flustered. Reinhard visits the Mariendorf estate, asking for Hilde's hand in marriage. Hildegard is unsure of his feelings towards her, thinking his actions may be due to Reinhard's own sense of obligation.
