Cora Lewis was the adoptive mother of Ryan Wilder.
At some point, Cora adopted Ryan Wilder from foster care, separating Ryan from her best friend Angelique Martin. Cora and Ryan developed a strong mother-daughter relationship over time where Cora helped Ryan graduate from high school, allowing Ryan to find a good job. As Cora raised Ryan, her adopted daughter came out as a lesbian, to which Cora was very accepting.
When Cora and Ryan moved into a new apartment, they were attacked by the Wonderland gang who killed their landlord before they murdered Cora. They attempted to kill Ryan, only to be stopped by the arrival of their leader, Alice who ordered them to leave. Once they were gone, Ryan tried to save her mom by using CPR, only to discover that Cora had died from her injuries.
After Cora's death, Ryan ultimately was reduced to living in a van with no employment. Ryan continued to mourn for her adopted mother and kept one of Cora's plants as a way to give herself some company and keep her mother close to her.
Ryan kept a photo of Cora with her plant in her van.
Upon meeting Alice, Ryan attempted to kill her to avenge Cora; Alice summoned a swarm of bats during their fight to distract and escape Ryan.
