A/N: I want this to end happily, so we're slowly going in that direction!
I'm not making it so that Emma is magically recovered from what the Evil Queen did.
She's choosing to forgive her despite that what the Evil Queen did is irreversible.

Before the Evil Queen realized what was happening, the trio had pulled her into the house.
Regina had helped her up the stairs due to her still being in shock and was standing in front of a closet.
"I know that you are from a different realm and that you don't wish to see your land ruined, but I thought that you can at least enjoy your time here when you visit Henry."
The Evil Queen was speechless.
"Once a year for his birthday isn't sufficient enough, you need to visit more if you and Henry want an unbreakable bond."
"What do I do about my kingdom? It can't be taken care of without a Queen."
"Perhaps we can make it so that you live here permanently. There must be a way to make it so your kingdom doesn't vanish.
Does Snow White and Prince Charming still exist there?"
"Yes, they do and they have forgiven me for the crimes I have committed."
"I recommend letting them rule your kingdom as well."
"I can't allow you three to let me stay here. It's not right of me to stay where I don't belong."
Emma put a hand on her shoulder.
"I know this place looks scary, but it's not. You said it yourself that where you're from doesn't feel like a home.
I'm sure if you sort things out back at your castle, then everything will fall into place.
After all, Henry wants you here and I don't want to keep him from you. Regina and I did that enough with each other over the years. It only lead to hurting one another."
Henry nodded, "Having three moms means more presents for me!"
Emma swatted his arm, "Be serious, Kid!"
"Sorry Ma! All I'm saying is that I'd love to have you added to our family. You might drive Ma crazy though."
Emma rolled her eyes, "I can handle two Reginas."
"I don't know Ma, Mom's a handful!"
"Henry Mills, if you say one more thing, then I will ground you for a week!"
"I'm going to college soon, you can't ground me!"
The Evil Queen had a small smile on her face as she watched the trio interact with one another.

The former Evil Queen had arranged it so that she no longer needed to be a part of her own world anymore. The Charmings had taken over her kingdom as discussed, so she was free to remain in Storybrooke. The other towns people weren't a fan of her, at first, but they opened their hearts and home to her.
There was weariness when it came to trying to cross the town line.
"We can totally do this in baby steps."
"Emma, she's not a child!"
"She's nervous and I would be too."
The former Evil Queen rolled her eyes, "I'm right here, you two."
She turned towards Henry, "Are they always this protective?"
"Yep!"
"They do this because…?"
"They love you, duh."
"That sounds ridiculous."
"They're ridiculous!"
"I heard that, Kid!"
"Henry, don't be a bad influence."
Henry held onto his third Mom's hand, "I'll be here the entire way with you. You can do this."
He bent down to give her a kiss on the cheek.
"What am I, Kid, chopped liver?"
Henry and the former Evil Queen made a face.
Emma held onto her hand while the other Regina held onto Emma's.
"As a family, we're doing this. One, two, three…"
The four of them walked over the town line and all four of them made it safely.
"Family vacation starts now!"
"Emma, we are not taking her in your death trap!"
"Death trap?"
Henry chuckled, "She means Ma's car."
The former Evil Queen was proud to finally learn and understand what he was saying. She even knew how to drive a car.
"I would prefer not to if it's referred to as a "death trap", so is there another way to travel?"
"My car."
Regina snapped her fingers and her sleek black car had appeared where they were with bags packed.
"We're going on a big adventure!"
Emma high-fived Henry.
She held out her hand for another high-five towards the former Evil Queen.
"High-five?"
When she gave her one, Emma wasn't ready for it.
"Jeez, you know how to kick butt! Next time, I won't ask you or Regina for high-fives."
The former Evil Queen laughed at how funny Emma was.
"Everyone in the car, please." Regina said.
After everyone was settled, they drove off into the distance.
The pain of the past was left behind and all that was left was happiness.
