You had died a couple weeks ago. All the boys were crushed and needed to talk to you. Just see or hear your voice one last time before you were gone forever.
So they searched for hours for a summoning spell. Meanwhile you were happy up in heaven. Ash had found you and you were currently having a beer with Jo, Ellen, Ash, and Pamela.
"Alright. We've tried every spell, if this doesn't work..." Dean trailed off.
Sam shook his head and lit the bowl on fire. You felt a strange sort of tugging. Something was tugging you downstairs. Then you were suddenly falling.
The lights inside the bunker were flickering and the whole thing began to shake. Then, it all abruptly stopped. You had arrived. You slowly sat up from the floor, and there were your boys.
"Cas? Dean? Sam?" You spoke.
Your voice echoed through their ears and all three smiled.
"Are you there, Y/N?" Sam asked.
"No duh dipshit." You stood up.
Your form began to flicker into view as you did. Then all three men could see your pale form.
"How is it upstairs?" Dean asked, a smile on his face.
"Quite nice actually. Ash found me and now I'm having beers at the roadhouse." You informed.
"The good ol' days. When we didn't have to worry about much." Dean chuckled.
"The only downside was we didn't know Cas." You laughed.
Cas smiled at your comment.
"How are you goobers gonna live without me?" You laughed after a couple moments of silence.
"I honestly have no idea." Sam answered.
"Were gonna miss you, kid." Dean told you.
"Well I'll see you permanently soon. You are the Winchester's." You informed.
All three boys laughed.
"But, I'll always be watching. Scolding you for letting one of the others get hurt. And yelling at you for your stupid decisions. So if you hear my voice, don't be alarmed, I'm just yelling really loud." You told them.
Your form flickered, and you knew it was time to go back.
"I love you guys. See you goobers." Then you disspeared.
All three boys were upset that you were permanently gone. They all blamed themselves for different reasons.
And you were right. They knew that they had made a stupid decision when they could faintly hear your voice shouting at them for their stupidity.
