i'm not saying you're stupid– i'm saying there are ways for you to see their children w/out having one of them be pregnant.
For example, a lot of the time, people adopt children that look similar to them (it's very eerie). Also, advancements in biotech are being made so that two eggs can produce viable progeny (while not directly relevant in this case, you could argue that this would be possible with two sperm eventually and set the story in the future).
Or, if we're focusing back in on this omegaverse, we already know that the security guard has omega genitalia and alpha disposition; therefore, he has eggs, which could be fertilized by Alejandro's sperm in vitro and implanted in a surrogate.
i'm gonna be so sad if the guard turns into an omega, alphaxaplha is such a good trope TwT
