If Neal ever comes back make him a villain! Not just any villain I mean the ruthless cold hearted evil sociopathic villain, make him Regina, Rumple, Hook all rolled up in one. Let him burn Storybrooke to the ground. Destroy their happy endings if its the last thing he does. Baelfire the Phoenix, Baelfire the Dragon, Baelfire the Hellhound. That way I am CERTAIN he will get a happy ending with his son and father, friends, and family.
I want him rising from the earth with steam coming off his body like this:
I want him kicking butt with a cross bow
And a staff
I want him to do this
and this happen
and this
Just a real nasty son of a gun
Sorry my love its the only way to get you a happy ending…
