What happened when...

That could be the best or the worst idea ever.

... Regina let her sister be free

She really didn't want to do it. Regina didn't hate Zelena as much as she did before, mostly because of this I-will-erase-you-from-the-story-and-my-life thing, but she still thought that the witch didn't deserve to be free.

Unfortunately, a certain god didn't really agree with her.

In fact, completely not.

They both tried to discuss, and find a way to do it, to succeed not to fight about Zelena being released or not. And she had to admit it, the god wanted to do it properly.

He could have made his "true love" - as Zelena was apparently that for him – escape from her cellar, and thanks to magic, but he didn't.

After all this Author's thing, he may realized that she really was important to him, and he wanted to build a relationship with her.

And of course, release her from where she was.

It has been two weeks since Isaac rewrote the story, and since things were back to normal, and the most of their problems seemed to become more and more worse.

At least, just one, the thing with Gold.

As time passed, he risked to become more and more impossible to control, and that was a big problem that they really had to stop.

But, back to the other situation, things weren't that awful.

Since what happened in the rewritten story – as Zelena apparently still existed at that time. Yes, Regina thought, that was weird – the other witch seemed to be... calmer than before. The strange thing is that she didn't yelled on Regina for having tried to kill her.

In a way, of course.

As her half-sister came to apologize, she just listened to her, as she never did before, a look in the direction of her own belly, with one hand on it.

That was the first Regina understood that her half-sister cared about her child. She didn't see it before, as Zelena didn't really show it, and the former Evil Queen thought that this future baby was just a way to stay alive, and have something against them.

Well, she had been wrong, after all.

She didn't trust Zelena at all, but she was still part of her family, and her remorse from the moment when she asked Isaac to destroy Zelena came again in her.

So, when she apologized to Zelena she was really sincere.

She wanted them to be a family, as she was with Henry, Roland, Robin, and other people as Emma, Snow, David – and also Gold and Belle, in a way – and regarding to who she was, or used to be, she knew that redemption's time would be long for Zelena.

(And was really her own redemption's time over ? She wasn't really that sure.)

The other witch still had anger, pain, and hatred in her, just as Regina did.

That was why she hadn't had the intention to kill her when they stopped her the first time, she really wanted to believe in her redemption.

Because then, it would be easier to believe in her own second chance.

But then, there was what Gold did, the time travel thing, the Marian thing, and the rest of it.

For the first time since Zelena' "death", Regina was really thinking that maybe the other Cora's daughter could be redeemed.
