Currently Erich and Erika were having a conversation which would change their relationship forever. And Ayumi was moderating it, to ensure that they were both able to express their frustrations with one another in a healthy manner.
At the start of the discussion Erika had made an admission, which, though shocking to Erich, seemed to be obvious to both Ayumi and Erika. She had confessed that she had secretly loved him from afar, and that he had betrayed this love by tainting his purity before their eventual marriage, and with an alien woman, no less.
Erich was stunned at this admission, and the fact that the woman was crying profusely, while apologizing for everything she had ever done to him. And though Erich accepted his wife's apologies, he felt as if it were a little late to properly subside his wrath.
Instead, he responded to the other portion of the woman's claims by voicing the absurdity of her anger.
