In Venus (1), Daphne introduces Archie to her only son Peter Stone, who is introduced to Emma and Manny Santos by them. Later Archie confronts Daphne at work about Peter's actions at the party with Manny. He makes it aware to her that the video of drunk Manny's breasts were leaked to everyone online or messaged, ruining her reputation, and getting her kicked out of her home. Daphne is confused and Snake tells her to call Peter into the office. When he arrives they discuss it all and Daphne is embarrassed and apologizes, giving Peter detentions.

Little did they know, Emma and Peter were looking for a secret place for privacy too. The teens see their parents kissing. Emma is filled with guilt when Archie tells her to keep it a secret from her mother. Emma tries to hide it but she doesn't feel right. She spills everything to Christine, and gets her very upset. She completely loses it. Not over one little kiss with a coworker- because Snake asked Emma to keep a secret, and that is unforgivable. She kicks Snake out, disgusted that he would use her daughter to hide his affairs and romantic life like that. Archie then ends things with Daphne, but a conflict between her and Emma arrises quickly when they see each other again.
