Castiel sat on a cloud in heaven, looking down on the people on Earth. He had his knees pulled to his chest and his wings wrapped around him.
He sighed softly looking at them but his mind wasn't on them really. While only two of them anyway. He conjured a wood stick and used it to spell his name on a cloud that drifted in front of him. He was thinking about how Sam and Dean always seemed to call him Cass, and it wasn't just his charges either, most other angels did too. Anna did, so did Uriel and Teresa, the archangel he had dated until recently.
There was a flap of wings and a gentle female voice hit his ears. "What's wrong Castiel?"
He looked up at his sister. Her name was Angel, her vessel had long black hair and silver eyes. Her wings were black to reaching her primary and secondary feathers which were red. He had not seen her in some time.
"Just thinking Angel."
Angel sat down next to him. "What are you thinking about?"
Castiel shrugged looking back at his name.
Angel noticed where his attention was. "Do you not enjoy your name being Castiel?"
"I like my name, father gave it to me. But I think my charges, the Winchesters, forget my full name, I think perhaps our brothers and sisters forget also."
Angel gave Castiel a confused look. "What do you mean?"
"They call me Cass not Castiel."
Angel giggled. "It's a nickname Castiel. It's a sign of endearment."
Castiel smiled a little this making him feel better, "I prefer my full name."
Angel smiled. "Then I shall always call you by your full name." Angel bumped shoulders with him.
Castiel smiled looking over her, "thank you Angel."
