Viewers can see what is happening here because they never missed an episode of Skeem Saam. Since Nothile sent a shocking message to Lehasa, viewers think that Nothile is already pregnant because they last saw her on the show in December last year.
Skeem Saam| Viewers are suspecting that Nothile was already pregnant before she left Lehasa

If she is coming back then she will be with Lehasa. Lehasa is very easy when it comes to women and she loved Nothile. What is Lehasa going to do with 3 women and if she is really pregnant, is he going to marry her too?

I think his uncle needs to step in because he will not be able to handle 3 women at the same time. Lehasa might be not in the relationship with Khwezi but it still counts, because she will always be in the picture. Nothile and Khwezi will bring the children to Lehasa.
