Dean Winchester was born mute. It was hard for Dean for the first 16 years of his life. No one understood why he could never talk to anyone, and if he was spoken to by a random stranger all he could do was nod or shake his head. That got on a lot of peoples nerves. The only thing that got him through the last few years of his life was Cas.
That's why Deans been going behind Cas' back for a surprise.
"Hey Dean, how was your day?"
'Work was a pain. Just looking forward to dinner tonight'
"Well I'm going to get in the shower to get ready"
'Dress nice'
"You know it"
Once Dean heard Cas step in the shower he pulled out the velvet box to open it. He was the only thing that got Dean through the rest of his high school years. Lucky thing Cas knew sign language, some reason that's long since left Deans memory.
"So, Dean, what restaurant are we going to?" Cas said as he and Dean got into the impala.
'Surprise'
"Let me guess. The roadhouse."
'Shut up' Dean signed as he started up the impala.
Dean turned up the music, making Cas grin like an idiot. They got to the roadhouse, with Dean going around the car and opening the door for Cas.
"Gentle many"
'Screw you'
"Maybe later"
Dean and Cas went into the restaurant with big idiodic grins on their faces.
They ate and talked about things when Dean was ready to show Cas what he's spent months on.
'Hey Cas'
"What"
Dean got down on one knee, opened the box, and struggled but said, "Will you marry me?"
