I always imagined that this took place after they all learned her name, but looking back, I realized Peter never calls her "Miri". Maybe he's not used to it yet. Or he just likes nicknames. Either way, I suppose :) Enjoy and let me know what you think!
The first person Miri kissed was Peter.
Now, when I say this, I must make something clear. Narnians are very prone to kissing. Most everyone kisses most anyone on the cheek. It's a greeting, a show of affection, of approval. It's happiness and joy in a touch. Lucy, in particular, is most fond of it. Foreheads are popular among close friends and family. Older ones will kiss the younger ones on the crown of their heads. Though Peter's siblings don't always appreciate it. Respect is shown by kissing the wrist or equivalent thereof. I suppose you get the idea.
So when I say that the first person Miri kissed was Peter, this is what that really meant: Miri had spent a whole afternoon sitting on the floor beside Peter's chair, as he struggled to explain to her the complexities of Calormane culture. When he finally looked down he was met with a blank look, though a small grin was lifting the corners of her mouth.
"You didn't understand a word of that."
"No."
"Why?" Peter exclaimed, hands thrust towards the ceiling. "Why do I even try!"
"Oh! No! It's my fault! I'm not good with learning." She got up on her knees, gripping his arm. "Please, I'll get it eventually. Don't stop teaching me, please."
He laughed, head thrown back. "You're a true joy to teach, even when you don't understand. Never fear, Little Flower. Ah, but how about you go find Lucy. It's a beautiful day and I think you've had enough learning for today."
Miri jumped to her feet and clapped her hands together. "Thank you!" And before either of them could quite register what she was doing, she'd planted a kiss on his cheek. They both froze for a moment, and then her cheeks turned bright red and she burst into tears.
"Oh, come now, Little Flower." Peter stood, pulling her into a hug, struggling not to laugh again. "What's wrong?"
"I didn't mean to," she sobbed, clutching his shirt. "It's just...you're so like...I didn't mean..."
"I'm like who, little darling?"
"M-My-Myriadd."
Peter was astonished, to say the least. He didn't know who this Myriadd fellow was, but he certainly meant something to the poor girl still soaking the front of Peter's shirt. Why would a simple kiss set her off so? He really wished she'd stop crying. He also wished one of the girls was around. He was fairly sure they could handle this situation a great deal better than he could. But he'd just have to make the best of it. "Come on, then," he murmured, gently disentangling her fingers. "Let's sit down again and take a deep breath, shall we?" Somehow he got her sitting in the chair as he knelt before her.
Once she'd calmed down a little and her sobs had died to little more than hiccups, he tried again. "Alright. Who's Myriadd?"
"My-my brother." She took a deep breath, finished with her crying, for which Peter was incredibly grateful.
That stumped him for a moment. "Is he still on the Lone Islands?"
"No." Hardly a whisper. Miri inspected her fingernails intently, till Peter carefully gripped
her fingers. She looked up, eyes wide, hands suddenly rigid in his own sturdy brown ones. She tried to pull away, but he gripped them a little harder and nodded. She sighed then and he let one hand go so she could wipe her nose with the handkerchief he handed her. "He's dead." She thought for a moment then gently touched Peter's cheek. "You don't even look like him. Except the eyes, perhaps. But you treat me like he did, and your laugh is his."
"I'm sorry." Peter didn't really know what else to say.
"I'm not. It's rather like a part of him is back, even when I thought he was gone forever. Somehow it makes me believe in Aslan that much more. If part of Myriadd is here, in you, why can't all of him be alive with Aslan across the sea like Lucy always says?"
Peter smiled. "No reason at all!"
Miri smiled slowly back, and brushed the final tears from her cheeks. "Well then. I've never told anyone that."
Peter stood, bowing as he extended a hand to help her to her feet. "Then I'm honored, my lady."
Miri's smile grew a little more as she gracefully accepted. Hands clasped before her, she stood a moment in thought, before standing on her tiptoes and kissing him once more on the cheek. "Thank you."
"Of course. It seems I've got another sister, doesn't it."
Miri suddenly laughed, joy ringing out where there had been sorrow but moments before. "And I've found my brother again!"
