If the McKinley Speedway survivors were each linked to the rollercoaster survivors.
Just for fun a headcanon.
Nick was at the tricentennial but was in the parking lot. He was gonna be attacked by a rottweiler but the evacuating crowd scared it away after they began freaking out from a girl killed by a flagpole.
Lori had to attend a funeral for her cousin Erin (on the Irish side of her family, hence them both having red hair) But the study where she did her coursework for college and routinely napped in at the same time each day caught fire.
Janet was delayed on the McKinley subway due to a crash. She later found out a stalker was a victim on that crash. A stalker she kept receiving death threats from.
Nadia's aunt and uncle called her and asked if she wanted anything to eat and she said she wanted Andy's drive thru. But they never got her order. The two teens in front of them screamed at them to back up due to a runaway truck. Investigators not only found drive thru hazards, but inspection of the inventory revealed to be foodborne illness that wouldve given her sepsis and dysentery.
Samantha's husband called her and said their son needed to be picked up from a field trip to a university that got cut short due to a gym accident where an athlete died. During her lunch break, she would've been electrocuted while doing her dishes in the employee breakroom, as coworkers the next day said it the coffee maker fell off the shelf into the water.
Andy was pubicly drunk and fell off the platform at the subway. He was found unconscious on the tracks. Train 081 wouldve run him over. But it never made it.
Carter's brakes to his truck failed. He wouldve been on the freeway when he noticed it. But he was passing by Phoenix tan salon as they were taking out Ashlyn's remains and was rubbernecking slowly past it because he was racist against Yuri and liked seeing his business fail, causing him to realize his brakes failed sooner.
Hunt gave his neighbors, the Freund Family, a gift basket since he used to date Ashley's older sister. He promised to help his dad with cleaning the gutters once he got back. The ladder his dad set up for him ended up breaking and he would've been impaled by a weathervane.
Jonathan's family leased some aerial lifts to the McKinley tricentennial. When Ian got crushed, he had to go assess the situation with his company's lawyers and see if his family were culpable. He otherwise would've been bitten by a snake on his family's rural farm with no one around.
George was the third person affected by the train crash. A young woman blocked his way onto the train because she was too busy talking to her sister in the threshold. He missed the train. If he got onboard and it didnt crash, then after the next stop he wouldve slipped off ice on the sidewalk and got his head squashed by a taxi.
