The full synopsis of the episode reads as follows:

Executive producer Leila Gerstein has teased how this unexpected event changes Zoe and Wade's romantic future.

"She's going to freak out as I think many people would!" Gerstein said of Zoe's surprise news.

Although Dr Hart will not reveal the news to Wade in a normal way, according to reports, Wade will find out what's going on with Zoe by the end of episode 2.

"Episode 3 will see both of them overreacting to this news in crazily inappropriate ways," Gerstein said.

"Finally, by the end of episode 3, they will have come around and there will be a major resolution as to what's going to happen between them and their child."
