S6E12 - "Abby Road"

This week, the flu is ravaging both the ER patients and its staff, Carter tries to get through to an angry child with a progressive illness, Benton has to bend the rules to get a little girl treatment for her scars, Cleo treats a boy who is using HGH, Luka resorts to trickery to prove a mom is abusing her son, and medical student Abby Lockheart joins the ER staff.
