Is Dr. Conrad Hawkins (Matt Czuchry) about to become a widower? He and his longtime love, nurse Nicolette Nevin (Emily VanCamp), tied the knot and welcomed a daughter in Season 4, but fans of the "CoNic" relationship were rocked by VanCamp's August bombshell announcement that she isn't returning for Season 5, which premieres tonight. (Another lead character, Shaunette Renée Wilson's Dr. Mina Okafor, also left the medical drama at the end of last season). Bruce Greenwood, Manish Dayal, Malcolm Jamal-Warner and Jane Leeves return to their familiar roles.
