Remorseful villainess Silke Beck
Silke Beck (Julia Dietze) was a villainess from "Home Is Where the Heart Is", episode 2.05 of Crossing Lines (airdate September 25, 2014). She was the sole female member of a biker gang, and the girlfriend of the gang's leader, Max. The gang was revealed to be serial robbers, and the episode's beginning showed Silke helping her gang rob the Deprez family.
To gain access to the house, Silke rang the doorbell and claimed she had been in an accident, allowing her other gang members to storm the house. However, rather than simply robbing the house, the violent gang members proceeded to brutally murder the Deprez family, much to Silke's horror.
As the ICC began to investigate the home invasions committed by the biker gang, Silke confronted Max about their latest heist, lambasting her cohorts (particularly Wulf) for their cruel violence and begging Max to let her out of the gang. Max then hugged Silke and asked her to get rid of the SUV they had stolen during the Deprez heist, making her believe he was going to grant her wish. But later on, it was revealed that Max had actually had Silke killed for trying to leave the gang.
