Is Sonia pregnant? And will Reiss want to be a father?
Whilst Reiss continues to think that Sonia has cheated on him, Sonia has no idea why he's so off with her and is still reeling over his comments about not wanting to be a dad, worried that she might already be pregnant.
Back at No. 25, Whitney supports Sonia as she takes a pregnancy test, but catches Reiss trying to hack into Sonia's phone, resulting in a furious confrontation. Devastated, Sonia reasons that Reiss wants kids, but just not with her.
Trying to win Sonia over, Reiss goes on a charm offensive, but nothing works until he's totally honest with her. As they have a heart-to-heart, what will the future hold for the couple?
