Disclaimer... I do not own Supernatural
So obviously Dean had a lot of guilt after Cas stayed in Purgatory. This is just Dean sending text messages to Cas's missing phone, thinking he's dead, and wanting to express his feelings somehow. Just something i wrote in my spare time, :)
Cas?
I miss you.
Why didn't you come home with me?
I need you.
Cas, please come home.
I don't know what to do without you.
Cas?
You're dead, aren't you?
Jesus.
Cas, wherever you are, I miss you.
I can't do this without you.
You've been there for us for so long.
I didn't appreciate you enough.
I'm sorry.
Thank you. For everything.
Cas?
I'm sorry.
In Purgatory, I was happy. Because you were there. Every day, you were there.
You were always there.
You protected me.
I should've protected you.
I need you.
I miss you.
I want you safe.
I want you safe with me.
Damnit, Cas.
That handprint you left… When you pulled me out of Hell. Sometimes, I swear I could still feel you holding me.
It's too late now, isn't it?
For me to tell you everything.
There've been so many secrets and lies and evasions with us.
We broke a long time ago, Cas.
I'm sorry we never got the chance to put ourselves back together.
Castiel…
Dear Castiel who art nowhere that I know, I pray that you are safe now, that you are happy, and that you have forgotten all about me.
You were better off before you met me.
You should have let me roast in Hell.
But damnit, I can't wish it.
I'm glad we met.
I'm glad it all happened.
I'm glad we were together for that short time, even though it was only as friends.
Castiel.
Where are you?
Did the Leviathans get you?
Did you die, way down there, with no one to hold you?
Are your wings scorched into rock?
I wish I was there.
I wish you were here.
I wish we were together.
If you're alive, and you find me, I'll tell you.
I'll tell you everything.
I'll whisper it in your ear, if you want.
I'll shout it.
I'll scream it.
Cas.
I love you.
