Had a tear in my eye after thinking about the end of that promo.Henry just can't die, he can't. So I am taking the “soap opera” out and say he is going to end up in the hospital. He is just too key to the story right now, and if he is trying to convince Emma to believe, I believe he took something shall we say “magical” that could kill him, but he believes Emma can save him, thus his “I believe in you” before he ate whatever he did.
