My prediction for season 3 of Offspring
Cleg, the evil attractive devil he is, goes on a shooting rampage, kills everyone but Nina. Cleg confesses his love for Nina, which has been burdening him all these years, he had to sit and watch her fall crazy stupidly in love with Chris, and when that failed he thought he had a chance, but then Patrick came in and stole Nina away from him once again, but in the end Cleg couldn’t stand it any longer, he needed Nina, so killed every attractive man in Melbourne. So anyway. He expresses his love for Nina and then Nina falls crazy stupidly in love with Cleg, Cleg proposes around mid season, the wedding is the season final, but because everyone close to them is dead, they have a nice romantic private wedding. The last scene of the season is Nina saying that she’s pregnant.
