So, while working on a new one shot, I wrote down "this is how her story ends" which made me think about season 4 and Isaac.

At the end of Sympathy for the De Vil (4x18), Snow and Charming find Isaac in Gold's cabin. They question him about his intentions, and he reveals that Cruella can't actually hurt Henry.
The part of the conversation I want to talk about is this:

Isaac: I had no idea that Gold would use her like this! Even I couldn't see the of the story.

Snow: What are you taking about? How does the story end?

Isaac: With the saviour... turning dark.

Now everyone thought that Emma was going to go dark after she killed Cruella but she didn't, and then she became the dark one and did go dark for a bit, but then she went back to herself and wasn't the dark one anymore... but the story didn't end. It's still going. The oracle told her that her story ends by getting stabbed.

So that's where I ask this. And I want your opinions on it:

Could the story ending Isaac was talking about be the same one Emma is seeing? If so, does "the saviour turning dark" mean Emma? Or does it mean Emma's alter ego?

Here's what I think is happening. Adam and Eddy have said Emma will be struggling with the after effects of being the dark one. Dark Swan is kind of Emma's alter ego. If, somehow, Emma does the same thing Regina did, and tried to desperate herself from that (or if she's trapped and it's done by force) there will be two Emmas. Dark Swan and Saviour Emma. Im thinking Dark Swan acts like real Emma and the Emma we see being killed is Dark Swan. Who kills her? The Saviour.

"How does the story end?"
"With the saviour turning dark"

The story of Dark Swan, something that had been "in the making" ever since the Charmings
took the darkness out of Emma before she was born comes to an end. Dark Swan's story is over, and it's all because the saviour "went dark" (hence dark cloak, murdering) and killed her. That could explain why her family just stands there and watches the fight go down, because you can't convince me that they wouldn't jump in and help, especially David and Killian.

Tl;dr: That conversation in season 4 has got to have something to do with what's going on. There's no way those two storylines don't have to do with each other, especially given the fact that they both talk about the saviour's story ending.

In other news, Sean Maguire is back! We don't know how or why yet, but several cast and crew members have been tweeting about it. I've said it before and I'll say it again, he won't stay dead. It's as simple as that. He deserved better, and they're not going to kill him off permanently. He has a now-orphaned son, and a newborn daughter, as well as a true love, that the writers aren't just going to forget about. He's probably gonna show up mid-season and be all "Hey bitches. Bet you thought you'd seen the last of me!"
