She read Snow White's letter first, recognising the different handwriting. She knew it would be awkward, but she hoped Peter would get bored and fly away before she got to Henry's or Emma's. There's were more personal.
Regina,
I won't waste words on the past. We both had a chance to talk on the journey to Neverland and sensibly avoided the hard subjects to concentrate on finding Henry. My mother was cruel to your mother, your mother killed mine. Anything we've done has continued a hatred they started, and with beings like the Dark One interfering in our lives, along with dark magic's, we would just be going around in circles.
You raised my grandson all these years, protecting him and keeping him on the path of good. Thank you.
I want to ask you a favour.
Emma is writing you a letter and Henry doesn't know the contents but I do. She has had a fight with Neal and is refusing to speak to anyone about it. Rumplestiltskin has woken, no longer the Dark One, and with little memory of that life. He calls himself a coward and won't allow Emma to try and use her magic to make him remember. We need him to remember. Neal told Emma about the promise he made to you and she wants to track down everywhere the Dark One went and fight anyone who might come after Henry. Rumplestiltskin refuses to travel anywhere, except back to Storybrook, and Neal just wants Emma to go home and not put her life in danger. They should be at home raising their son. Eventually Henry will grow up and Neal thinks that once he's not a little boy he will be safe. Rumplestiltskin only worried about a boy causing his downfall, if he gave them Henry's description the way he did to Peter, whoever's out there will only go after him while he's a child.
Emma has called Neal a coward and refuses to come home and hide with Henry. I want you to tell her that is exactly what she has to do. She keeps muttering that you will help her, that you're the only one who understands, as though you're the only other person who loves Henry. We all love him and want to keep him safe.
Please send her a message, reply to her letter, do whatever it takes but please convince her that she mustn't risk dying. I can't loose her again.
If you can't do it for me, then do it for Henry. He needs her, Regina.
Snow.
"What do you think?" Regina asked Peter, looking up from the letter.
"She's right. The same way the Lost Boys wouldn't want to lose you if you could stay."
"But if Emma's right and there are other things coming for Henry… She'd need my help to get to Rumplestiltskin's memories."
"Are there no other magic users in Storybrook who could show her the spell?"
"The Blue Fairy. Maybe she could use the magic from her wand."
"There you go. They don't need you. If Snow White is a Queen can't she order her armies to go and fight instead of her daughter?"
"I suppose."
"Read Henry's letter next."
