and I though the way they later on addressed that uncertainty of what exactly does having wonky DNA entail("Can I have kids?") felt real and not commonly seen in shows like this.
I found that question from Jennifer a little odd. I mean, she has the same powers as her father (just orange instead of blue), and the fact that she exists to ask the question proves that her father was able to have kids. So it follows that she should be able to as well.
I think the more appropriate question there would've been, should she have kids? Knowing that superpowers are a hereditary trait in their family, would she be willing to have kids, knowing that they would grow up to have powers and face the burdens/responsibilities that come with them?
