Synopsis by Hal Erickson
This episode marks the final regular ER appearances of Eriq La Salle and Michael Michele. After resorting to desperate measures to retain custody of his son, Reese (Matthew Watkins), Peter Benton (La Salle) realizes that he must make a choice between the boy and his overloaded ER schedule. He opts to take a less demanding job at a clinic in the Chicago suburbs, where his current love, Cleo Finch (Michele), is already working. In other developments, a boy accidentally shot by his mom on Christmas Eve is a cause of great concern amongst the ER staffers; Abby (Maura Tierney) sees Nicole (Julie Delpy) where she didn't expect to see her; the relationship between Weaver (Laura Innes) and Lopez (Lisa Vidal) enters a new phase; and Carter (Noah Wyle) receives startling but not unexpected news about his parents.
