In the season two finale of Once Upon a Time, Neal is (nonfatally) shot and falls into a portal, which then closes. When Emma sees her family, she tells them he died. Why does she say this? He was clearly alive when he fell into the portal, and Emma herself made it back to Storybrooke from a portal! It is possible that she wanted to protect Henry from having any false hope, but, again, Emma was able to come back! It seemed pretty obvious that Neal wasn't dead, and at the end of the episode when he is revealed to be alive seems a bit weak.
My question is this: Why does Emma say that Neal is dead?
