Synopsis by Hal Erickson
After surviving a robbery and physical assault, an interracial couple (Raviv Ullman, Jurnee Smollett) begins suffering from severe abdominal pains. House (Hugh Laurie) suspects that the similarity of symptoms has a special significance, hidden deeply within the couple's complicated past. Elsewhere, House gets sore when Wilson (Robert Sean Leonard) begins spending his spare time with a new nurse (Kimberly Quinn). And in a story development with longer-ranging ramifications, Cuddy demands that House apologize for his rude treatment of patient Michael Tritter (David Morse--who turns out to be a police detective with a singular talent for holding a grudge.
