A/N: If Cas were to leave so soon again after returning...
"Hold on...So you've just come back and you're going to leave again? Already?" Dean asked Cas in an incredulous voice. They two weren't standing as close to each other as they usually would.
"I'm sorry, Dean, but you need to listen," Cas said. He didn't want to leave either, but something was drawing him back to heaven.
"No, you listen," Dean snapped angrily, "You told me that you might kill yourself if you ever went back to Heaven. Then you did go back, and you didn't reply for weeks Cas! Weeks. I thought you were dead and I was worried. Okay? I was completely beside myself! And you finally come back, but you tell me you're still suicidal! Well guess what, Cas? I don't want you to leave me, so don't you dare kill yourself! Don't you even think about leaving permanently. Ever." Dean now had tears in his eyes. He was just so angry and furious and overwhelmed with feelings he was only starting to understand. "I love you, Cas. And staying here for me is enough reason to put aside your suicidal tendencies."
Dean found himself standing extremely close to Cas, as they usually would. He noted that the Angel looked close to tears, so he calmed down. Dean cupped Cas' chin into his hand and said gently, "So go to Heaven, but you better be back soon to tell me that you're still alive."
"Of course," Cas said and then hesitated, as if he had something else to say. Instead, he disappeared and Dean closed his eyes and sighed. He prayed silently to God for Cas to come back soon.
