New episode up... and two "ER" theories

Last night's "ER" had the return of Dr. John Carter and it wasn't all hugs and puppies. When he was alone he had this look of pain on his face and I even remarked to myself "What is wrong with him?"

Seems he is having kidney issues. The weird timing thing of tonight's episode was that it was Valentine's Day. Well, it was also the Valentine's Day episode, many years ago, where Carter was stabbed and got the kidney issues to begin with. Way to connect things.

The episode also dealt with a woman needing a heart transplant, but she has Type O blood.

Well, a quick Google search told me that Carter has O blood as well.

So either they are going to be killing Carter off. And that's how they are getting all the cast back... for a funeral.

Or, this woman is going to die and Carter will get a brand new kidney out of it.

Either way it will make for great television.
