Castiel had always been observant, especially when it comes to human interactions and gestures. He did his best to learn and observe hoping to bridge that gap between angel and human.

So, when he was passing by a boutique, he overheard a bubbly conversation between two women. They discussed which flowers conveyed specific meanings; lilies for purity, roses for love, and lavender for devotion...

To say the least, he was intrigued that these tiny plants could erupt with such extensive meanings. He had walked by so many in his lifetime without a second thought; it was the small things that mattered, too.

It was only within the day that he had returned to the bunker, returning to them with a soft flutter of feathers, making his presence known. He held a bouquet in hand, spilling out different colors, sizes, and shapes of flowers.

He extended the collection of flowers, a gesture that he had come to enjoy, a way to express himself without the need for words.

"I wasn't sure if you'd like this, but I bought all the colors they had." His lips quirked into a gentle smile, and his gaze warmed. "Each one is supposed to mean something different."
