Forced to take a mundane and degrading job slinging burgers at the Doublemeat Palace after realizing her family were in financial ruin, she sinks into a deep depression amid feelings of self-loathing and spends much of the season on a downward spiral alienating her friends and family and embarking on a violent sexual relationship with the vampire Spike which leaves neither satisfied and spawns dire consequences for the both of them.
