As Jack was pretending to ride a parked motorcycle and talking to it about how he would like to own it, Sierra and a friend caught him in the act and mocked him for talking to what she thought was his motorcycle. Flustered, Jack tried to explain away his embarrassment while also flirting with her. When two cars, seeking out the motorcycle, appeared and threatened to run them over, Sierra and her friend fled. Darkness Rising, Part 1

Another day after school, she tried to take Jack up on his offer of a bike ride. They were interrupted by Vince, who challenged Jack to a race. Sierra and her friend accompanied them to a road outside town where they held a race, and Jack easily won. Sierra and her friend spread word around school, and she later told Jack she was impressed with his racing skills. Jack subsequently felt compelled to accept Vince's second racing challenge: Take part in an illegal street race. Sierra acted as starter and waved to Jack before the cars blasted off. The next day, she again asked Jack if he'd give her a ride. At first he turned her down, but changed his mind a short time later, and they whizzed through the streets of Jasper. Speed Metal

At some point, Sierra left a message on Jack's social network page about his race with Vince. Crisscross

Confused by the fact that she never saw Jack outside school, Sierra paid him a visit at his after school job at KO Burger, but was unsettled when he was picked up by a leather-clad woman on Jack's motorcycle, whom Jack claimed was his mom.
