I think he won't be present in the episode, because he's still resting and healing. Or maybe he's still in coma? It's hard to say, especially like Delkolover said, that the spoilers often change and they may not be complete.
Maybe after Man Down they realized it was a mistake to let him get back to work so early after such a serious surgery. So now they are doing it properly and Eric will be absent from work longer, just to make it more reliable. I think it wouldn't be a bad idea. It's just I'dl ike to see him during his healing proces.
As for Eric and Calleigh's break up, well that'd be definitely too much for me. If they want to do it, I'll be very disappointed and mad:scream:.
But I really hope they don't do this to us. It'd be too cruel. And for me watching the show wouldn't be such a pleasure anymore.
