Kurt is 80 years old now. He has the last stage of Alzheimer's and he doesn't remember Blaine anymore. He's frail, and sickly. His children know he's going to pass on at any second. They almost wished their dad wasn't able to remember either so that he could escape the pain of losing his husband. He wasn't able to speak anymore. So when it came time for him to go Blaine was by his side. He finally remembered in his last moments his husband. The recognition was in his eyes but try as he might he couldn't speak. He couldn't say the words that meant so much to them for such a long time. If he could just say the words then he could go.

"It's okay. You don't have to say it. I know it isn't goodbye Kurt. I know. It's okay. I love you so much. Just let go Kurt. It's okay to let go. I love you."

He looked into Blaine's eyes until he couldn't anymore. Suddenly a younger version of himself was watching his husband cry over his body. He watched his daughter turn to bury her face in her brother's chest and sob. He touched them all one last time before he walked into his mother's arms and they both disappeared in a subtle flash of sunlight streaming from the window all the while never taking his eyes off of his husband and his children until he was out of sight.

"I'm never saying goodbye to you."
