the dead meme in question:

These are Ira's parents. From left to right we have AlacrĂĄn, this world's god of death and the afterlife, she is thousands of years old but has only recently woken from a 500-year-slumber, she can only be perceived by the living when they are close to death and at the darkest hours of night.
Next is Emilio Velazquez, Ira's dad, who has had his soul permanently stuck between life and death for most of his life, he had Ira when he was 23ish and he and AlacrĂĄn grew distant as he got older and she got used to the modern world and they settled into a co-parenting dynamic.
Finally, we got Talia, a biologist, who very stubbornly doesn't believe in ghosts, souls, or the afterlife and who is also Emilio's wife with two kids. Whenever confronted by the paranormal, she either rationalises or studies it, if a study results in something that seems paranormal, it requires more study. Ira having angel wings and sometimes turning into birds or a skeleton have required long-term study. Along the way she developed a pretty good relationship with both Ira and AlacrĂĄn, who both enjoy her perspective even if she makes theories about them being mass hallucinations.
I'm not 100% sure on what their dynamic is specifically how Emilio and AlacrĂĄn feel after 25 years of co-parenting, but them being an on-and-off thruple isn't out of the question.
