Meanwhile, the teaser also gave out a hint on which character will have a baby in the upcoming season. In the clip, it seems that Toby and not Daphne or Bay will be with child in season 4. However, nothing has been confirmed yet by the series creators.

In a previous interview with E! News, Marano previously revealed that she is looking forward to the pregnancy storyline that will be explored in season 4. At that time, fans immediately speculated that it is either Bay or Daphne that could be pregnant.

The actress also urged fans to watch the upcoming installment because it will be huge and powerful. She said the same things when she talked about the controversial rape storyline that aired in season 3.

At that time, Marano's Bay was allegedly raped by her good friend Ty. Although Ty swore that what happened between them was consensual, Bay argued that he should not have taken advantage of her because she was drunk.
