Also, when one of Lu's patient's ex-con husband returns home after more than three years in prison, he may be suffering from more than depression. Meanwhile, Andy considers taking her relationship with Dr. Morton (Richard Biggs) to the next level while Lana's (Jenifer Lewis) life is turned upside down when someone from her past returns. Dr. Biancavilla (Brennan Elliott) faces a moral dilemma when a paramedic friend is pricked by an IV drug user's needle.
