Merlin had been sick for a long time; no one knew what was wrong with him. Not even Gaius. They had all been praying for a miracle. But nothing happened; Arthur had been sitting by his deathbed when he had died. He was holding his hand and the last words that escaped his mouth was "I'll always love you"
Arthur was sitting quietly opposite of Gaius, holding a cup of tea in his hands, it had gotten cold.
"I'm sorry for your loss, Arthur" Gaius said quietly.
Arthur looked up "I'm sorry he didn't get his miracle"
Gaius smiled gently "He did, it was you"
Arthur finally let himself cry.
