They met when they were in college, bonding over a similar perspective on life. They both wanted to just "live", whatever that may entail. While Alejandra was an ambitious creative, Amir had a passion for basketball. As they aged, these dreams and pursuits would falter as they realised they were parents, too.

As a couple, they function like life partners. Their relationship isn't especially romantic or sexual, but they are both content with this. They trust and respect each other and don't really desire anything more than what they have. Out of the two of them, Amir will be the one who occasionally wonders what it would be like to be in a passionate marriage, but he's still content with how things are.

Born when his parents were 19 and 18, Andrew was brought up in a home that didn't necesarily want him there. He was unplanned, but so was his sister, so that didn't particularly sting when he learned of it later in life. Amir had read Andrew as being an independent child, and so freely left him to his own devices. This backfired, for the most part.

As a thirty year-old man, Andrew does not carry the resentment he once held for his parents. He used to hate them, but this dissatisfaction was able to dissipate partly due to the jading effect of his prison stay. He also came to understand that his parents were just teenagers when they had him, and clearly didn't know what they were doing. Still, he was a bit frustrated they didn't seem to have learned their lesson with Nessa, given she was raised only slightly better than him.

When Amir learned his wife was pregnant in the dawn of her thirties, he approved of her decision to continue the pregnancy, knowing she wouldn't be able to for much longer. Like their first child, Nessa was not planned (clearly). As Nessa grew, Amir was happy to see that she shared interests with his wife, since he had failed to inspire an interest in basketball in his eldest son.

Nessa doesn't view her parents as caring much about her and ignore them as much as they do her.

When their daughter befriended Janiyah, Nessa's parents were happy she had a friend. They appreciate her quiet and respectful nature, mostly attributing any teenage behavior she's a part of (like sneaking out or staying up late) to be Nessa's own influence.

Janiyah is a bit intimidated by Nessa's parents, but doesn't have any negative feelings towards them. She's suspicious, due to Nessa's disposition towards them, but they're nice to her regardless.

More details are to develop

When learning that their daughter's friends, along with some other local kids, supposedly ran off, they became fearful. They were worried it was a repeat of what happened last time, where instead of their disappearance being some act of rebellion, it was instead a red herring for their deaths. They were thankful that their remaining son suddenly (to them) became responsible and sought after them, even encouraging him to do so.

Living in the town that they did, the Karis knew that Vincent (as they knew him) was a strange kid. Despite one of the landlords in town claiming to be his guardian, they had heard nothing of the teen's existence before recent memory. They did not know anything significant regarding Isolde, though she reminded them of Nessa based on what they did know.
