Traffic Lights! Or just Jacob Malory before the whole apocalypse happened with The Visitor coming to Earth. He was a Road electrician fixing the wires and street lights. It was while he was tranporting a box of various lights that, he witnessed the Visitor and mutated into a snake ish creature covered in light bulbs of all sorts. He lives in the same apartment building as Ivan and visits the cat cafe on the ground floor often after work in the hops of seeing the short twink who he had gain a crush on, but was always too afraid to confess his feelings to the man out of fear of being rejected.
It was only till he mutated that his crush turned problematic as he began spying on Ivan in hopes of keeping the man safe from harm only to find out that Ivan too had mutated into a dark inky squid creature with glowing blue lights. But instead of being horrified Jacob simply fell harder in love for Ivan becoming obsessed and willing to do some questionable things to have Ivan become his. That was when he had heard about another cursed/witness known as The Surrogate and there unique ability. So Jacob carefully waited for when Ivan gotten a bleeding wound after a fight while gathering supplies and offered the man some bandages to help patch him up, and when Ivan later threw those away, Jacob collected them and went to go find The Surragate to give them the bloodied bandage and a sample of his own blood to have a child.
Now it takes a LONG time for the child (Abby) to form due to the starkly different and complex natures of her parents mutations and by the time she's fully created The Surragate would've learned about Jacob's problematic crush on Ivan and decides that they can't leave the little one in Jacob's care. Luckily they did find out that Ivan being a school teacher and all is really good with kids and figures they can trust the poor Ink Squid man with the baby. Cue Ivan one day opening his front door to see a cursed holding out a baby snake fry cyclops and learning he's her dad. Of course once he got all the shock out of his system Ivan immediately calls for his sisters help and learns how to take care of his new daughter he names Abby.
