There was skip in her step and a light in her eyes; Lily was happy. Now, it wasn't like she had never been happy - but she certainly had never been this happy when surrounded by her family. She was so excited in fact, that she decided to greet most of them. It even struck her that she ought to greet Bella - since she had never done anything wrong and Lily had, until that point, always been rather unfriendly towards her.
Lily made her way over, she smiled at Rose and Bella. She noticed at once the demeanor on Rose, and before Rose had a chance to resist, gave her a hug and a kiss. "Merry Christmas." Lily wondered if Rose would wonder if someone poisoned her or something. But truth was - Rose looked like she needed both.
"Bella," she said, not exactly sure how to greet her. "I'm so glad you're here," she said authentically, namely because she was happy. For so long she had thought of Bella as having stolen her Albus, but truthfully Bella had just made him happier. So if Albus was happy, she could be happy too.
