I had a whole blog on their story and their family in a much older save/game. https://sims4pancakes.blogspot.com/
In my latest/current project, a Sim of mine (named Breanna Fox, the cheerleader in my avi in fact) met Bob at one of those random dance parties. In due time she convinced him to leave Eliza. Now they are engaged (but, actually, not married yet). They have a toddler named Natasha and Breanna is pregnant to Bob for the second time. MCCC tells me it is twin boys. Right now they live in an only slightly redecorated Pique Hearth, but with three preschoolers and two bedrooms, they may need to consider moving.
