Synopsis by Hal Erickson
Rachel (Hallee Hirsh) accidentally causes Elizabeth's (Alex Kingston) infant daughter, Ella, to OD on Ecstasy. Abby (Maura Tierney) gives shelter to the battered Joyce (Christina Hendricks), incurring the terrible wrath of Joyce's husband, Brian (Matthew Settle). Carter's mother (Mary McDonnell) tries to make belated amends for the death of her other son, Bobby, by lavishing care on young leukemia patient Mickey (Colton James). Victims of a letter bomb are brought into the ER. Gallant (Sharif Atkins) treats a blind man, despite being allergic to the man's dog. And Romano (Paul McCrane) angers Weaver (Laura Innes) by apparently giving preferential treatment to Lewis (Sherry Stringfield).
