How Many Tears Are Enough?

Kara lands herself a new job as caretaker for the Luthor's. She's to take care of their youngest daughter Lena, who's been forced to move back in with her mother after a devastating explosion at her job, causing multiple fatalities and her brother's incarceration, nearly killed her too. That's been a year ago and physically, Lena is fine, but she has a severe depression and needs someone to look after her. That's where Kara comes in. During her time with the Luthor's she slowly finds out there's a little more going on, though.
