Is the ER episode featuring the return of Anthony Edwards going to be ridiculous and unrealistic, or will it have long-time fans appreciate it? -- Megan
Ausiello: Worry not -- your favorite hospital hasn't turned into a dead-raising hellmouth. Dr. Greene only appears in flashbacks, where we learn the tragedy behind Dr. Banfield's (Angela Bassett) thorny exterior: Greene couldn't save Banfield’s son from a particularly bad case of acute leukemia, and he died in the very ER she now works in. Ouch, right? We also get a brief glimpse of our old pal Robert "Rocket" Romano (Paul McCrane). Don't blink, or you'll miss 'em.
