Noah Wyle returned to ER last week.
It was an exciting event for long-time fans of the show, but will it end up being a tragic come back?
At the conclusion of the episode, Carter collapsed and was subsequently hooked up to a machine. We can now confirm that this was a dialysis machine, not a chemotherapy device.
Also, look for Eriq La Salleto reprise his role as Dr. Benton around the time Carter really needs some help.
Does that mean Carter is guaranteed to have a happy ending? Not at all. But his prognosis could be a lot worse, that's for certain.
