I was so hoping that Lois would explain about her marriage this part, but it was not to be.
However I think I have an idea. The Bangala can't deal with the idea of an unmarried person who does not have parents. For someone to have any part in the tribe they have to be married. Lois and Matymbou got married, but agreed it was just to give Lois a place in the tribe, and never had any intentions of anything else.
Lois is trying to get Kent to not worry about it, but it is just too outside his understanding to think of Lois as not married when she said she is.
The more we learn about Lana the worse she is. That she let him think it was his baby she was going to have is just so horrible. She is the worst possible, pure evil.
I love the interactions of Diddi and Kent. I love how Lois is trying to let Clark be part of her family, even if he does not realize it yet.
I do hope Lois manages to tell Clark what is really going on.
