Credit to: mine-everything from Tumblr for the idea. She pointed out that Snow still thinks that the wardrobe can only take one, so when they set out to find it did she plan on only sending Emma through? That's what I think anyways. So here's what came of my thoughts on it.

My darling Emma,

I know that once you find this, we will have been forced worlds apart-at my own hand-and I am so very sorry for that. I vowed once that I would never lose you again but I have come to realize that if losing you means that you will be safe, then any sacrifices on my part are well worth the pain and suffering. I understand if you resent me again, knowing that I've left you to return home alone, but please try to forgive me someday.

Maybe now you will grasp why I was so forward in my attempts to get to know you along our journey to the castle. The minute I realized that there was a chance to get home, but that only passage for one would be possible, I knew that I'd be forced to send you off alone. Most likely against your will. But please, Emma, before you blame yourself or build your walls even higher, know that I didn't abandon you. I needed you to return home. To Henry. And you father. They both need you, more than you know.

Henry, he's such a fine young man. You should be proud. But please, just try to picture if it were the two of you in this situation. And before you get angry and think that it's a completely different story, that Henry's just a child, I will tell you it is not at all different. Henry is a child to you, just as you are a child to me. My child. Though you may be a strong, radiant, and brave, grown woman now, I will never be able to look at you without seeing the baby I held in my arms for mere minutes before she was whisked away. And I hope you can forgive me for that.

Know this, Emma; from the minute I knew of your existence, you have been my world. Even in my years under the curse I believe I was always searching for you. There was void in my soul as Mary Margaret that was only filled once you became a part of my life. I don't think I ever knew the extreme strength of love until you. I remember spending nights talking to you before you were born, I'd sit out in the cool air on the balcony off your nursery, and just tell you stories. Some of them were about my life as a young girl, losing my own mother; and at the time I had promised so fervently that I would never allow the same to happen to you. How cruel fate can be.

But other times I would tell you stories of the future. The many adventures we would go on, your first lesson on how to ride a horse, or Red and I teaching you how to track, and—not without argument on my part—you father showing you how to wield a sword. But none of that ever came to fruition. For that I am sorry. But those are things that mattered more to me than they ever would for you. You spent your entire life without someone to hold you, or comfort you, or scold you in the way that only a loving parent can. And for that I am more sorry. Every moment that you experienced pain, the ones you had clued me in on as your roommate, or the ones that have gone unspoken for years, I wish with all of my being that I could have been there for you. My sweet, beautiful, Emma.

There is so much more I wish to say to you, knowing that these may be the last words that I ever send your way, but I cannot seem to make more. I promise, to my death, I will forever search for ways to get back to you. But in order for me to do that I need YOU to promise ME something. Do not do the same. Allow yourself to find happiness, don't risk your own life to try to return to me. There is no way, you know that. And PLEASE Emma, do NOT dwell upon all the things that went unsaid. I know you, you'll spend months thinking of all the things you never said, you may convince yourself that I thought you hated me, or that you didn't love, but Emma…I know all of those things are not true. I'm your mother, after all.

One last thing, my dear Emma. I love you. I love you, I have always loved you, and I always will. You, despite what you may think, deserve more love than this universe can even offer. I am so unbelievably proud of the woman you have become, you really are so much like your father and I, and yet your own person. Do not ever doubt for a second that you were wanted. Sending you away was the most difficult decision I have ever had to make, and possibly my greatest regret. And yet I know it was still the right thing to do. Without it you wouldn't the daughter that I see sleeping next to me as a write this. The daughter that warms my heart in everything she does and is.

My greatest hope is that before I force you to leave me, I get one more chance to hold you in my arms. To stroke your golden curls, and feel you hold me back. There is no place I would rather be. You keep me moving forward. Always.

I love you Emma. With all my heart, with all my soul, with everything I have.

Don't ever forget it.

I love you,

Mom

Salty tears drip onto the paper leaving painful craters of moisture. Snow wipes vigorously at her eyes and tries to compose herself before her daughter awakens to take her shift to watch the camp. Watching Emma sleep she can only help but hope that her daughter can forgive her one day for what she's planning to do once the wardrobe is in working order.

Getting to her feet she walks over to the blonde silently and kneels down to place a soft touch on her cheek. "Emma. Emma wake up. It's your turn."

Her daughter stirs and rubs the sleep from her eyes with the meat of her palms. Once she notices the identity of her awakener her face brightens softly and a hint of a smile plays on her lips. Snow offers her hand and helps Emma stand, letting her fingers linger before releasing and taking Emma's place on the ground. She curls into herself tightly and forces her eyes to close. What's ahead is unbearable. But it's for Emma. She has to remind herself of that. That squirming baby that she grasped in her arms. The child she never got to raise and will never see again. It's all for her.

Emma.

I hope you liked it! Reviews would always be greatly appreciated.

And if you like this sort of theorizing, check out my tumblr (same as my author name). I do most of it there. It just bled into a fic this time :)
