This is mostly discussing Brian Hill’s Batman and the Outsiders series from 2019, it’s a really good series, would absolutely recommend. Through the series it is implied and outright explicit whether they are interested in each other.
Now I actually really enjoy all the scenes of Black Lighting and Katana together, really brought my interests in Katana as a character and coming from a Black Lighting fan, I really enjoyed having him discuss the things he says mostly to himself in his own comics with other people especially other heroes.
It was different from what I usually seen from a relationship because whether it was going to become romantic or not. I could appreciate how close they were toward the end.
From the gecko, I assume from #1 that they were going to get together, maybe during the annual but they never did and that’s okay. I’m not sure if people would agree but I kinda like them together.
