Every day, there's an important event written on Danny's arm. Or, at least, his parents and Jazz say they're important. Danny was just happy to be getting to know his soulmate through the ever changing soulmark.
The event written on his arm was the most important thing to happen to his soulmate that day. They helped him understand what it meant when his mark told him that his soulmate learned they were never going to see his parents again. They worried with him when his arm said that his soulmate's uncle got rid of his soulmate. They got upset with him every time it said that they'd run away from foster care, every time it said that his soulmate was hurt by the foster families. They comforted him every time the soulmark on his arm told him that his soulmate almost died. Sam, Tucker, and Jazz were there with him the day the mark on his arm said "Became Champion of Magic".
His soulmate stopped having near death experiences as often after that.
Billy had tried to check his mark every day, but most of the time it was rather bland. His soulmate had a very bland life. Other than the occasional "parents exploded something" or "got shoved in a locker" their life sounded amazing. He was kind of jealous. Not that he thought being bullied was easy or anything, but he didn't want to be homeless or in the shitty foster care system.
He became very worried when "dies" is written on his arm and is very confused when there continues to be more important events written on his arm after that.
Ok, so I read a Spideypool fic that used this same soulmate au idea, but after Wade died the first time Peter's soulmate mark morphed into Wade's fingerprint and only told Peter if Wade dies that day or not.
What if, Billy's mark for Danny morphed in a similar fashion and only told Billy if or even how many times Danny dies that day?
What if it was Danny's that morphed and only told him how often or if Billy was going to be hit by lightning?
