Cas stood confusedly staring down at an object in his hand. He had been standing in this position for over an hour, not that Dean had been counting or anything. Dan stood, closing his laptop, and walked quietly towards Cas, so as to look over his shoulder.

"Cas, what are you doing?" Dean enquired.

"I am doing what you humans call 'Texting'. But, I do not understand how…" Cas responded, turning his head so he was facing Dean.

Dean smiled slightly, and, rolling his eyes, he reached around Cas to hold the phone. "Would you like a demonstration?"

"Yes please."
"Who is it that you want to send the message to Cas?"
"You."
"Me?"

"You, yes you Dean."

"But why?" Dean asked confusedly, "I am standing right here, you can just say it too me."

"Yes, but, I wanted to make sure…" Cas paused, "I wanted to make sure that if I got it right I would know straight away."

Dean smiled, "Okay, now that we have gotten that bit out of the way, I want you to watch closely."

Dean then demonstrated how to create a message, how to write a message, and then, how to send a message. When the demonstration was over, Cas turned himself to properly face Dean. Dean went to remove his arms from around Cas, but he was stopped by the Angel placing his own arms around him, "Thank you Dean. I understand now." Letting go of Dean Cas turned and walked towards the door, "Goodbye Dean."

"Wait!" Dean exclaimed, but Cas was gone, he had flown away.

That night, Dean was awoken by the message alert on his phone. Sleepily, he rolled over and saw a message from Castiel:

"Dean, I think Zachariah was right. I love you Dean."

Dean smiled, "I love you too Cas, wherever you are, I love you too."
