A/N: I had to rewrite this because originally Susan was the narrator watching her mother and Peter with Lucy, but then I looked up the Narnian timeline and found that Susan would have been four or five years old, which didn't quite work. But despite that mix-up, I think it turned out fairly well.
Prompt: One of the friends of Narnia (or a Narnian, if you like) learns their colours.
"Lucy." Peter's young voice called little Lucy back to attention. I smiled at her wide, innocent eyes as she watched him. "Look over here." He motioned at the colored squares of fabric on the floor. "Which one's the yellow?"
Lu's golden, curly head tilted to the side for a moment, then with a happy baby chuckle she pointed to the sky blue square.
"Almost!" Peter exclaimed from where he sat across from Mum and Lu on the carpet. "You're amazing, little Lu," he nearly cooed, making me bite back a smile. His relationship with Lu was so cute.
Something clattered in the next room and I started to my feet. There hadn't been any glass shattering, which was good.
"Edmund!" Christopher's voice called to him, and I sank back onto the sofa again with a sigh. No matter how many times we went through it, the amount of things two year olds could reach was astonishing.
On the other side of the sitting room, Peter scooted closer to Lu. "Do you know what's yellow?" he asked her, picking her up in his arms and cuddling her.
"No!" She shook her head gravely, then burst into laughter as Peter began tickling her.
"The sun's yellow… buttercups are yellow… your hair is yellow!" He ruffled it as she twisted on his lap to look at his face.
"Li'ns!" her little voice exclaimed.
Peter nodded, grinning. "That's right, Lu! Lions are yellow. Good job!"
My eyes strayed to the lion statue on the mantel. I'd always found it to be noble, yet terrifying…. Lucy loved it though. Christopher lifted her up sometimes so she could gently touch its stone mane.
Another round of cooing and applause from Peter brought my attention back to their game. Lucy was clenching the yellow cloth in her fist, waving it triumphantly.
