After having 10 Seasons and 2 Movies and 2 Spin Offs and several Novels and Comics. There are no storylines of what did happened with Jack and Laira.
Because that seemed pretty rude to her and her people. If she got pregnant by a guy from another planet and he got away. Because he did visit her planet again to visit a planet expose the Rogue NID later named the Trust.
To make a point clear, not talking down on Jack. While come on. Not as much a mention of a woman that can be pregnant with their child.
Where I was not happy what happened with T.J's pregnancy and Vala's pregnancy that did had storylines to an end. I liked Teyla's pregnancy.
